99% of Players Make THIS Deckbuilding Mistake in Yugioh

[@Testosjerome]

Thanks for the video! Could you explain the underlying math a little bit more? I really don't understand why we assume exponential growth of the probability to see at least one dupe. Isn't it just the # of playsets times 3,64%? For eight playsets in my 40 card deck, drawing a 5-card starting hand, I draw at least one dupe with a probability of 29,1% (I think). Where does the exponential growth come from, seeing that the cards/playsets are independent from each other.

[@JessePerezStrategyGaming]

The best way to visualize this without being confused by numbers is this. Imagine you have a 42 card deck and 14 playsets. We will take the draw of 5 one at a time instead of all at once. To start you draw your first card you have out of 5. We will call it A. (A) draw has to doge itself on its second card. Now we draw card 2 you have to dodge copy of A with 2/41 chance to draw a dupe. Say you dodge and draw card B. Now on your 3rd draw A and B BOTH have to dodge thier respective dupes. Which means now 4/40 percent chance to draw a dupe on draw 3. (10%) Your 3rd card you draw is C. Now your 4th card has you have dodge A,B & C and you have 6/39 chance to draw a dupe. Now the forth card is D. That means your 5th card odds to draw are dupe is 8/38. Which that draw alone is 21% When you take all of these factors together you have about a 33% chance of dupe. You can see how because their was a guaranteed chance of getting a playset card in your hand it now made things exponentially worse. If you drew a non playset card like a 1 of then that card "draw" is safe and won't effect. Therefore the more playsets the deadliest it is. Your 5 card hand will become 4 in about 1 in 3 games if you have 8 playsets I can show this math on discord but this one takes a long time so bring popcorn.

[@Testosjerome]

​@@JessePerezStrategyGaming Ahh, now I see where the misunderstanding comes from. With exponential growth, you are referring to the number of cards drawn from deck. The number of playsets in the deck itself does not contribute to exponential growth in the probability of duplicates on a starting hand of 5. In fact, the probability per playset decreases slightly due to the cases where you draw two duplicate pairs. So, let's take the example of 40 main deck and 5 hand cards: The probability of having at least one duplicate in hand depending on the number of playsets is: 1 - 3,6% 2 - 7,2% 3 - 10,8% 4 - 14,3% 5 - 17,7% 6 - 21,2% 7 - 24,5% 8 - 27,8% 9 - 31,1% With 8 playsets in my 40-card deck, I therefore draw a dead card in over a quarter of all games, provided I always go first. If I go second, i.e. draw 6 cards, the probabilities look much worse due to the exponential growth depending on the cards drawn that you mentioned: 1 - 5,4% 2 - 10,6% 3 - 15,7% 4 - 20,6% 5 - 25,5% 6 - 30,2% 7 - 34,7% 8 - 39,1% 9 - 43,4% If I draw 6 cards from my 40-card deck, that contains 8 playsets, I will have a dead card in my hand 40% of the time! To summarize, the probability of having duplicates in the starting hand increases exponentially with the number of cards drawn and (almost) linearly with the number of playsets in the deck. The number of playsets in the deck raises the exponential curve to a higher trajectory, so to speak.

[@lautaromonsalvo8808]

@@JessePerezStrategyGaming you are correct about this math. But there's no exponential growth here. Each playset that you add has roughly the same chance of getting you a dupe that the previous one. So there's no reason why you should stop at X playsets or whatever. The cost on them is linear so if you think the 9th is bad, the 1st one is also bad

[@JessePerezStrategyGaming]

@@lautaromonsalvo8808 there is exponential growth. I made a video specifically going into great detail on it you can find here. kzbin.info/www/bejne/lXrEaqOnbqtnmJI

@@JessePerezStrategyGaming The probability of having at least one duplicate in hand depending on the number of playsets is: 1 - 3,6% 2 - 7,2% 3 - 10,8% 4 - 14,3% 5 - 17,7% 6 - 21,2% 7 - 24,5% 8 - 27,8% 9 - 31,1% Can you see how each playset that you add, increases the chance to dupe by almost the same amount? There's no exponential growth there. Playset 9 is as bad as playset 1, they both increase duping by 3.6%. Any rule where you have to play less than X playsets is nonsense because playsets don't get marginally worse as you add more.

[@neotemporal]

-Ash and wanted have NOT been hit in the tcg -Veiler and imperm are not once per turn, so they are still good to draw multiple of -oversimplifying too much because you are not taking the gameplay of the deck into account. snake eye doesnt care about drawing multiple starters because they often need to discard a card. also drawing wanted/diabelle/bonfire on top of one card combo is how you play through handtraps. they are both starters or extenders and necessary during this handtrap heavy format -prank kids needs kids in the deck to summon them. if you dont have 2 of a type in the deck you cant xyz summon that level (ie if you draw 1 of them and only play 2). also they are good to draw in multiples because you can fuse with the ones in your hand and save bodies on the board. not every deck is based on one card combos. labrynth is another good example. good deck building involves understanding how that specific strategy functions and optimizing that, rather than focusing on a specific magic number of starter/nonengine cards -if you run 12 starters, and play 7 rounds of swiss, about 3 games you will draw no starter. probably not going to top doing that. better to see 2 starters some games than have too many games where you cant play, at least in a tournament all that being said this is a good overview of how ratios will affect your starting hand, and the diminishing returns, especially for those new to deck building; you explained it well. i do agree people focus a bit too much on consistency (like always running 40) and less so on other things, such as how well you can play around hand traps/breakers, what nonengine people are playing at the moment, knowing the weaknesses of other decks in the format and how to counter them etc. these things are more instrumental to the success of top players than consistency alone

[@rhyned]

This! But this is not getting any love by Jesse. I believe this is a valid point.

[@JessePerezStrategyGaming]

Sorry for late reply wanted to make sure I address everything as this was a great comment! Sorry ash is limited in MD and OCG & wanted is limited in MD. It is very hard to remember the exact forbidden limited lists for every card in every format. This point was really just a point of interest and not really a major point i just spontaneously said that because it was on my mind at the time. Apologies for the error nonetheless. I thought I mentioned that the playset rule only applies for cards that are HOPT effects. If i missed that then apologies also. Which is why i didn't have imperm in the original playsets. I do talk about imperm specifically how that is good and doesn't follow the birthday paradox but that was in another video and not this one so i might have gotten that confused but yes non HOPT wont be counted to the playset rule/birthday paradox. I could have went further in depth on prank kids but i didn't want to confuse the audience with what pk did and just was using it for a general example. The math does change if you go in depth with prank kids as they can even preform certain 2/3 card combos, the discard with fansies or the banish and draw 1 with rockies or the +1 with plan at the end of the turn benefit thinning strategies. But so many people would be confused and i made an artistic choice to deliberately leave that out as prank kids was not the point of the video. Ultimately, It seems like it came at the cost of confusing the more well known players and skilled players especially those who are skilled at using prank kids in favor of helping those less versed in prank kids. However, Not drawing a starter though in your round of swiss example doesn't automatically equal a loss. If you have 0 starter that means your 5 card hand is all tech/handtraps which is likely enough to force a simplified gamestate and get you another turn at which point you have a big chance of gettiing your starter topdeck or side engine rolling (adventure/kastira as used in example) All in all great points and I agree. Well written comment and well said! Thank you for watching I appreciate comments like these the most.

I take your point that you were just trying to show a clear example of not playing too many normal summons as starters basically. branded comes to mind as a good example of this, some players only play 2 aluber for this reason. perhaps it would help in the videos to have a clarifying statement like “there may be other reasons you choose to play more starters in a deck, like if the cards have other uses, but this is an example of a starting point when deck building to not have too much engine”. or something like that if that makes sense. would help to clarify the snake eyes bit too. glad to see thoughtful discussion from you in the comments as always Jesse.

[@earthteamjordan]

Running only 12 Starters means you brick 15% of the time which is acceptable casually, but if youre playing competitive then you need your Deck to do its thing more than just 85% of the time. Diminishing returns is real but I don't think it applies

[@thiccupcake]

You should play prospy which can be either a starter, extender or non engine

[@kenshi1985br]

you run engines and other stuff, better than have a higher chance of being ashed and loose 2 to 3 cards in hand because you are hyper consistent

[@earthteamjordan]

​@@kenshi1985br Unless all your starters are normal summons, then that won't happen. Like if you're playing Invoked then you don't play too many normal summons. However there are plenty of starters that are spells and special summons. Also, even in a deck like Prank Kids, imagine not opening a single Prank Kid 1/4 games, because you're afraid of a hypothetical hand trap. That's not good deck building theory. If youre afraid of hand traps then max out on starters, extenders, and cards like crossout/talents to keep playing. Don't just cut your starters

[@FakeGuthix01]

Yeah it's not diminshing returns because while the percentage gain decreases as you get closer to 100%, the value of each percent also increases. 95% consistency (brick 1 in 20 games) is literally twice as consistent as 90% (brick 1 in 10 games) consistency. The increase in consistency is actually linear with the number of starters.

[@YeahTheDuckweed]

something i remember hearing from johnny li in a true draco sky striker deck profile on cimo's channel was something along the lines of "too many starters and your deck will be consistent but weak, too many extenders and your deck will be powerful but bricky"

[@Dreadlash]

For the Snake-eyes cards I'm not sure this is the best exemple Diabellstar is both a starter and an extender (so is bonfire) and this would actually change the math because it's great to see 1 Diabel, 1 wanted or 1 bonfire on top of your first starter (the card has multiple uses) The Prankids exemple is perfect though

@@rhyned Not to mention, if you use Pandemonium you're locked into Prank Kids names, which means you can't always reliably go into those strong game-ending link monsters (Borrelsword, Accesscode, etc.) Often Prank Kids will run over 2 turns, and therefore needs more than of each name (Unless you're running Plan to recycle, since you can't always rely on getting to your one copy of Pranks) Besides, all of the Prank Kids can summon from deck OR hand, so yeah- you'd rather have a hand trap in hand, but they're not bricks in hand... There's a reason why literally every single Prank Kids top ran 3 of all of the names besides MAYBE Rocksies. The math may be there, but math isn't always the answer. Sometimes logic is.

[@deviltrigger02]

I don't deny there are a lot of players that just simply add everything related 3x or simply max copy everything without any thought like just putting a pile of related cards together when comes to deck building, which usually means bad, and you did have a point on the part on the concept of "better choice". However , the main thing about this ain't as simple as "you got starter you are good", it is about "do you really need those in 3 copies?" or may be even "how many copies of this card do I need?", "will this amount of copies synergies each other or just brick me when all drawn to the hand?". 99% hyper consistency is not necessary means bad, it really depends on will it brick, or just can have other uses when multiple of it drawn to hand. Take snake eye as an example. You got diabellstar, blue snake eye, bonfire into the hand, it is still not a bad hand as you can just thrown a card for diabellstar, summon blue snake eye search for kurikara, bonfire into red or may be other useful things, in the mean time you can even force trade your opponent hand trap if you got so many starters. Snake eye got like so many "starters" , but it is never brick due to how flexible it is to the point your opponent has to force their hand trap into your cards so that you can never get that much of value before it start snowballing. The case become slightly different when comes to prankids. Prankids themselves are bound to consume big slots as it don't actually works by themselves if just play to field without legal targets in the deck, which means you pull 1 prankids to the hand, 1 less you can recruit from the deck because of how prankids works. You got 3 prankids in the hand, which can also be bad if you summon 1 and leave the other 2 doing nothing. However , I want to mention if you have a prankids fusion or equivalent in the hand , multiple prankids become somewhat acceptable instead of a bad brick as you save a normal summon while you got 2 or may be 3 pankids to the field which can leads to big board if play properly. Things can even get complicated if you run rank 3 or/ with adventurer engine as well. you can link 2 into burning abyss dark fairy for a set of adventurer while allowing prankids, to build a bunch, transition into apollousa, and may be with a thunder dragon fusion into boss prankids follow up by a thunder dragon colossus, depending on build and situation, which may leads to more complicated when considerating the copies of the same card in the deck as well. Also , I will want to mention with this amount of generic searcher nowadays, there is more to consider when comes to card drawing. Chicken Game and Upstart is good by paper because it can means a -6 to your deck size, but that is assuming you are able to play it on your turn. If you go second, those cards literally doing nothing on your opponent turn and just stuck there. If your deck aren't blind second oriented, those are actually pretty bad if you go second and want to interrupt your opponent turn 1, especially you pull a hand trap that is good for opponent first turn instead of other things on your going second game. If i play a deck that is running heavy hand traps that is good to disrupt opponent turn 1, I will not want to use this in the place of hand traps that allow me to disrupt opponent play on opponent turn 1. Furthermore, there are spells, it also means that the card that synergy will be different as well. It is more synergy to decks like sky striker, spellbooks or decks running reasoning/monster gate that needs to stack spells on the graveyard which in current card pool they are either underwhelming power or just don't see much synergy with majority of decks as majority of decks are more monster oriented rather than spells. Also, 6 slots of the deck space can be a lot, might be better to include another engine depending on deck type and build as well. Hence, if you want a good consistency, frequent testing on pulling the first 5 cards and see will it brick becomes important when comes to deck building (thank god master duel implement this feature). You can hardly build a decent deck without some sort of testing and filter out those bricks as sometimes things are not that obvious and interrupts from your opponent can make things even complicated when comes to consistency.

[@JessePerezStrategyGaming]

You are absolutely correct, there are certain 3 card combos in PK like have 2 kids and a fusion that work for hyperconsistancy. The math for 2 and 3 card combos are different. For 2 card combos you want to run between 20-23 starter/combo cards to get that 85% range. You CAN build your Prank kid deck to facilitate this style of play and this can work as well if you want. For simplicity sake i didn't want to confuse the audience that were not familiar with prank kids and go into the fusions - can banish 1 with rockies to go +1 the discard with fansies etc. So I deliberately left this out as an artistic choice so i wouldn't confuse but you are absolutely right and if this video was an hour I would certaintly touched on your points. Funny enough I did not do did math for 3 card combos yet as it seems like you would need to run so many cards for it to reliably work that I treat it as a bonus and wasn't worth my time to do the math but I might do it in the future if I get more requests for it. I also completely agree with your take on upstart & chicken game. My goal was to say that chicken game should not be taking the place of a handtrap and i hope that point got across.

I initially put 3 ash in my zombie deck because “that’s what everyone else does, surely that must be correct” despite starting with all 3 in hand means you bricked. I put it to 2 with 1 ghostbelle and it actually improved my consistency a little. Then a ran 1 copy of 3 different ghost girls and now if I open all 3 I now have something I can do on either turn! My deck likes to go synchro or links so having only a handful of tuners was nice. Even now I’m still experimenting with my zombie deck like if I even WANT bacon saver or tri-wight in the deck.

[@four-en-tee]

One of my biggest challenges as a deck builder is often trying to figure out how much engine I need in my deck, mainly because it often depends on what you're piloting. Most decks want to have plenty of space for non-engine, and the type of non-engine depends on the deck. For example, i've been messing with Shining Sarc lately, and this deck cares a lot about including handtraps and quick-play spells for non-engine since it synergizes with Future Silence. But if you're playing either a mishmash of archetypes or just a ramp or combo deck in general (insert obligatory jab at Branded players), the engine to non-engine ratio isnt always very clear because in some instances, you're basically falling back on either extenders or a secondary engine as opposed to non-engine pieces. I think an excellent example of this is Live Twin Runick Spright. While its not seeing a lot of meta play right now, this deck is honestly all about establishing a big ass board of monsters. It generally wants to play through disruption as opposed to playing more non-commital, and when going first, it often tries to either Iblee Lock the opponent or set up a bunch of roadblocks (like IP to go into cards on the opponent's turn like Apollousa or what have you, as well as in-engine disruption like Trouble Sunny). On top of this, your generic disruption is also a part of your engine in the form of the Runick package.

The idea in this video is what came into my mind when I think about YGO deck-building recently, because nowadays pretty much every card/effect is hard once per turn. So, it must be better to run 2+1 copies instead of 3 copies of something that do the same thing, right? And with the amount of cards in YGO now, I believe it's not that bad replacing the third copy with another card that serve about the same purpose (albeit most likely a little bit worse, or different, like Upstart Goblin). All of this makes sense, and your video thoroughly explains the idea. Very nice video. I like all the math inclusions as well. Well done.

[@JessePerezStrategyGaming]

Yes finding consistency in other ways is very important especially as the pool grows. Especially the odd 1 ofs that might be very useful - that you won't find in Netdecking! For example - if a player plays a horus deck/diabelle or adventure engine? Consider a single copy of metalfoes fusion as discard fodder! A single copy of Metalfoes fusion will draw a card after your plays and serves as a great draw 1! It also goes great in say decks that use "foolish burial goods"! Oh do you already have your Rainbow Bridge of Salvation and foolish burial goods in hand? Now instead of FBG being a dead card we have a 2nd target in Metalfoes fusion! Powerful mathematical decklist building is what can separate a great deck from a good deck!

[@overcoldice]

​@@JessePerezStrategyGaming Damn, you mentioned Metalfoes Fusion there. That's my favorite one-of back when I still play YGO. Especially in any deck that wants to play Foolish Burial Goods. Twin Twisters was a very good spell back then, so, easy discard target as well. Metalfoes Fusion, whenever I read the card and was deciding to add it in my deck, I struggled to find any reason not to. In fact, when I'm thinking about the card now, I'm still struggling to find much reasons. Of course there's the reasoning like, what if you draw it without any way of dumping it? But come on, Knightmare Phoenix exists, though I don't know if this card is still relevant. I wasn't that great at YGO back then, not like it has changed much, but I was worse. And due to this, when I debated whether to include Metalfoes Fusion or not, 40-cards deck "limit" won, and my playsets of what I thought were "important cards to run at 3" won. I was so anti on the idea of 41+ cards decks, and overvaluing the staples a lot. So, looking back at those times now, I feel happy, I was dumb and now I know better. I just wish that YGO would print their cards in better formatting. Instead of slapping a paragraph of microscopic glyphs below a charming work of fine art with some fancy name above that artwork. When cards become more readable, like how I believe it is in OCG, maybe I'll consider YGO again. Right now, I simply can't bear seeing a brand new archetype (to me), combo-ing to what seems like infinity, with me busy reading cards one by one. It's not a fun experience for me. But YGO deck-building, or maybe puzzle-solving in general, is a pretty fun experience. I mean, recently I'm playing some single player YGO games, where I got to build a deck with whatever format there is and whatever cards there are. Pretty fun, and I don't need to read that much. Damn, sorry, I ended up writing a lot. xD

[@ezkhel]

I'd love to see a video on 2 card combo decks! For example, a deck like virtual world have varying ratios across multiple deck profiles. Some play 3 of each name, some play 2 laolao/lili, some play 2 of the spells, etc. Maybe there is a list that runs the most optimal amount of engine and tech cards so that you see your 2 card combos most of the time as well as some amount of tech cards.

Thanks a lot. I'm gonna watch all your content now. I'd love to see you build decks as well while explaining what you do.

[@AuratticStride]

For the 8 playset rule, it could have been articulated a bit better, but basically the more playsets you run, the higher chance your hand contains doubles. So its a 3% chance of drawing 2 red prank-kids but it could be like a 20% chance of drawing two of the same prank-kid (red, blue, green or brown) which is why your chance of essentially 4 card hands goes up

[@AuratticStride]

[@JessePerezStrategyGaming]

[@Lorens4444]

Great video! However, I should probably add some things: 1) Some cards alter the statistics in this video. Chicken Game and Upstart Goblin, for example, would reduce the "real" number of cards in your deck and allow you to run 10-11 starters instead of the mentioned 12 depending on the number of these draw spells that you play. 2) You are absolutely correct about Swordsoul running 8 playsets being a bad thing, but only until you start taking Pot of Desires into consideration. XD

[@SkyPopePhoenix]

As someone who took a college stats class recently, yeah, all this sounds accurate. Cannot describe the number of people who get confused by the math behind probability when seen on paper vs practice.

[@BokuNoShousetsu]

I really love these videos, I think taking this kind of maths approach to deck building helps know you just got unlucky and the issues isn't that you just build your beck badly. One suggestion I would add is at the end of these types of video it would be nice to end on some kind of very clear, actionable application to everything you explained - somethings the application of this gets a little lost in the details. For example, a potential application of this video (if i am understanding the explanation correctly) would be to avoid playing a playsets of a card if its effect is once per turn, and you can change out 1 copy from the playset to other card that does a similar or the same thing. Playsets of cards should be saved for cards that a absolutely essential for the deck to function or have very high power level (I assume something like Maxx C would fall into this category). Or put simplify, if you never want to see 2 copies of the same card in your opening hand, to lower that chance from happening, only play 2. A practical example would be - x3 "Dark Ruler No More". I almost never want to see 2 copies of that in my opening hand, so instead, replace the 3rd copy with something like x1 "Ultimate Slayer" or x1 "Droplet". I think that what we are trying to say in this video - but let me know if I am wrong.

[@slackergod8464]

Its crazy to find out that when i made decks i was indirectly always avoiding making my decks hyper consistent its like finding out something u do everyday has a word to sum up what u do and u never knew the word

[@lucanalon1576]

I loved your discussion on upstart and chicken. Those are meant to replace multiple copies of (HOPT) cards you can only play in your turn. I remember a custom format turnament of MBT where Pot of Greed was at 1 and some lists were not playing it, that was poor deck building to me.

[@JessePerezStrategyGaming]

Wow that is insane to me that people are choosing not to play PoG!? Even in the most consistant of decks you could still do your plays then do the draw at the end. So shocked. If this tournament was played on MD, Maybe they didn't have the UR dust to spend because thats the only way I can see them not playing PoG

[@autobotstarscream765]

​@@JessePerezStrategyGamingPoG is king, to the point of making it worth blowtorching your Deck to get to Pot of Greed for 2 of whatever was left, hence why Pot of Desires was so big, and if experience playing older formats, especially running Salamangreat around the time of TOSS Format, hyperconsistency was only ever used in Exodia Decks until Desires changed the math for a lot of people, and their gameplan became open at least 1 starter and 1 extender in every opening hand at all costs so they could drop a Desires without worrying about what they banished face-down or getting any of it back, because whatever they banished after their initial combo pulled 1 of everything they needed out of their Deck would be either a redundant starter (basically a Garnet), a redundant extender (basically a Garnet), or a non-engine card (no good to you in the Deck until you draw it), because drawing 2 off 1 card and getting the +1 was always worth it while using 1 to draw 1 was just asking to get Drolled, hence why the popular play in Salami was hyperconsistency + Desires, and everyone I saw running Swordsoul was also running Desires to pop off Chengying and get those precious draws for a +3-4 off one Spell after doing their initial combo to pull out 1 of everything they needed to not lose to Desires in order to play, and so it almost feels like now people are building hyperconsistent Decks while forgetting why they popped up in the first place, as almost nobody's running Desires anymore since it was eclipsed by Extravagance and then Prosperity.

[@kermitdfrog1739]

Great vid, math looks good and the graphs are awesome. I do think the way you are phrasing your argument is a little awkward. The point of having super synergistic cards is so that one can have a "hyper" consistent engine using as few cards as possible. I think it's very intuitive to say that having massive amounts of consistency is not worth the loss of deck space, and by extension utility. The graphs present the optimal ratio for maximizing consistency while minimizing the number of cards used. Taking my intuition and then giving numbers that back it up and add specifics. Great vid, just earned a new subscriber.

[@JessePerezStrategyGaming]

Thank you! Comments like these really make my day!

[@JohanLucain]

I'm really glad you came back to the normal summon topic and dwelled deeper into that. Your videos are always helping . At least those have helped me to break away from some 'rules' with actual statistical data and concepts when it comes to deckbuilding. Especially the playset one. I assume that one applies only to hopt cards right?

[@JessePerezStrategyGaming]

Yes! the playset rule ONLY applies to HOPT cards. So for example, feel free to play as many copies of imperm as you want as that will not count toward this rule.

[@tobiasfrey2793]

While I mostly agree, I'd like to add that hyper consistency itself is not a bad thing - it only is if all the cards you add above like 12-15 cards are doing is add consistency to your one main strategy. However, there are a lot of engines you can add that can fulfill different roles in the deck. The one I'm currently playing around with the most is the Allure Queen engine, since it can be a starter for so many different strategies, but it can also act as a security engine (getting Herald of the Arc Light out within 3 summons) and it can also help break boards going second, since you can easily get a Light and Dark Chaos Angel out with it. If your deck is super linear with its starters then yeah, too much consistency is not a good idea. But those decks usually fold to like 1 hand trap, anyway, even if they can occasionally put out insane, literally unbreakable boards.

[@squiglythegoon9678]

I would love to see the math on 60 card decks, I'm playing an HEAVY engine based deck that feels perfectly consistent, but I'd like to see how I could fine tune the exact ratios

[@JessePerezStrategyGaming]

I made a video with how to build a 60 card deck with math in it here: kzbin.info/www/bejne/bmHOc3V_esmLjJo hopefully it answers all the ratio questions you have if it doesn't leave a comment or find me in discord and ill try to help more.

[@DuncanHarbison]

I think this makes sense for general theory about ratios but sometimes drawing dupes isn't such a bad thing. I'd rather have 2 prank kids and play with a 4 card hand than have 0 and not be able to play. Sometimes cards are powerful enough that you want all 3 and you're going to draw 2 and that's ok - if I could play 8 copies of soul charge I'd throw all 8 in every deck I play for example because its so powerful that I'd rather have a dead second copy for a turn than not have it.

[@driptcg]

Yeah. I like these vids cuz having insight to the actual math is, well, insightful, and can play into how u deckbuild. But definitely as a viewer and player you gotta be able to discern the theoretical math from actual deckbuilding nuances.

This birthday paradox thing in yugioh could be a magnum opus or college thesis.

i havent played for 20 years! got into MasterDuel and I liked the cyber dragon deck. I bought all the URs n looked at similar decks and I literally run like 2 engines. this video solves my issues! I got to Platinum like a cakewalk but then my deck was no longer viable lol

I like how you explain this. Im still tweakin my Voiceless deck. Cz i dont like my ratio rightnow depend on my local meta with so much deck variant. Playing diviner build is bad on my local.

Diviner is such a great card, it has so much utility! if it can send a fairy to the GY and not get negated it can get so much value! Not to mention the tribute effect or it can also be a tuner too!

[@nightknight498]

I've spent a good while now trying to math out Ritual Beasts after the new support. The deck has an incredible amount of 1-, 2- and 3-Card combos, access to Emergency Teleport which acts as starter, extender or interruption depending on the hand and has synergies with a lot of different engines, all while having enough space for nonengine as well. It's just a complicated mess of a spreadsheet and trying to figure out and test different ratios is a pain.

[@d.r.6177]

The only thing chicken game and Upstart bait out is Droll, which messes up everything else you want to do as well

[@JessePerezStrategyGaming]

currently droll is played at >13% representation and assuming those that play droll run it at three copies that gives about a 4% chance that you will be drolled in a random game. That low amount is too low to be considered a threat at this point but that is good to keep in mind for future and past formats. In formats where droll raises from 4% to 15% or more (like some heavy search superheavy sam formats etc.) then you can consider watching out for droll. So for now I wouldn't worry about droll. Its like telling OCG or Master duel not to play Maxx C because of Floo its currently seen too little and counterable. Also, you don't have to do the draw 1 first. in fact its better thin the deck then do the draw at the end because your likely to run into more Tech/handtraps/traps yourself to futher boost your followup turns. Finally, if you did decide to use the draw first it still could be a better play to bait ash and have a total smaller decksize in cases where ash is used.

[@YellowFraggle]

Amazing vid. Couple minor mistakes imo but breaking down the ratios especially in graph for was super useful. Would love for 2 card combos and ratios on 50/60 card decks broken down too

[@swaee3]

Thats why alot of ur starters not only start but also continue your plays, think w sky strikers, ur starters r raye, roze, engage, hornet, linkage, and even the field spell however not only are they starters they also help you play your turns after

[@issuedname]

what was your metric for judging the range of probabilities to highlight in green for the starter ratio graph?

[@residentgrey]

Your thoughts on the Duel Links format could be crucial. I find going to two is better for most cards, and I primarily run 30-card decks. The 8-card ED means that you will rarely have more than one of anything there too. There are a lot of 20-card builds that can do some work but end up being glass cannons.

[@Xiu83]

I've been coming across this when making random yubel decks. The cards you'd normally run at three are dropped to two or a single copy in order to open up more fluent hands instead of bricking every time.

[@Beiyuu]

[@samdeoliveira6272]

Now, I’d like you to show an example of a rogue deck with a massive engine like Hero. What are the ways to cut down on deck size and what are the optimal ratios for starters extenders hand traps or board breakers? How would you account for an extra deck monster as a starter, such as Destiny hero dangerous? Spells count as starters too such as fusion destiny and foolish burial.

[@jkteddy77]

I'm a huge Infernoid fan, and with the deck coming back, I'd love to see analysis of 60-card decks, ESPECIALLY those with archetypal bricks Similarly, discuss "when to go over 40" like we're seeing with Rescue-Ace profiles

[@ZekeTheThunderWolf]

This is why recently i decided to play more than 40 cards in some cases. If all I have is engine, then sure I can have some tech cards, but if all I draw is engine and then my opponent does something crazy like use Maxx C or have board breakers, my one play was countered by the tech cards simply because I lost the coin flip and my opponent had just an ok board going 1st, but couldn't even play going 2nd because my single summon and magic card were both denied.

[@Nakata2021]

another problem is the kind of starters. For example the deck with a lot of starters today: Snake-Eyes - We have the Normal summon Starters: Ash+Poplar. The problem in having a lot of "Normal summon starters" is obvious, you have 1 normal summon for the turn, if you got both you actually got 1. The deck where this was common, Spright. Any 2 lvl 2 is a combo. So if you go for a lot of monsters that on normal summon summon another one from the deck you are safe? no, since you can only make 1 normal summon. - Special summon Starters: Diabell, They don't cost turn resource to play. The major example is the banned "Mathmech Circular". In the later YCS RIO the "melodius" engine presented its power too - Starters that work as Extenders when hand trapped: Bonfire + Diabell. The "crème de la crème" of starters. This usually go along with the later group. You start with ash, get imperm... well, Bonfire and go on.

[@notthing6692]

i kinda want to know how is the application of the 8 playset of birthday paradox on cards like effect veiler and inperm since they are not "once per turn" card

[@JessePerezStrategyGaming]

Yes! I should have mentioned cards that are not HOPT do not effect the 8 playset rule. Meaning a asset of Impermanence will not count to the 8!

[@SheruMuko]

While watching this I was comparing the deck I use which is @Ignister. It has 11 one card starters. Of which 8 are Normal summons or ways to get to them or get an extender from the deck. 6 normal summons are one card starters. 2 are extenders that if they are in your hand at the same time are a full combo as well. 4 different Cyberse type monsters that can be used as Link material easily. 12 hand traps. I don’t own 20 of them. Two garnets that I don’t want to draw but are needed for the deck to function. One of them is a pseudo garnet as I can search it from the deck if I draw the other. I need both for it to work. My friend hate that deck because it is too strong for them. It seems like I was following the same logic as you. Except I opted for more stuff to counter my decks counters. Hand traps are good in all when you’re using them but when your deck crumbles from a single hand trap you need to have something in place to let you keep going. Which is why I run more extenders in my deck over hand traps as well as anti hand trap cards such as Prohibition, Called By, and Crossout. Is my deck meta? Most certainly not as I am one of a few players who pilots the deck. Especially after a major engine got hit badly. I used Mathmech Circular as an enabler for a very nasty 13 interruption combo. Five negates, multiple bounces, quick effect destruction, hand rip, and revival from the graveyard on command. If I had a copy of S:P Little Knight add another two interruptions. But sadly the deck did get hit badly. I have been tinkering with it for so long that my friends are tired of facing it. Now if I want to duel them I have to use a structure deck. Disappointing really. I would love to hear your thoughts on this type of deck. My side deck is in the same ratios as my non engine so I can swap them out for different matchups. I also run a few hand traps that hard counter my own deck in there as crossout targets. I also play other card games where you can run up to four copies of each card in the deck. In those games there is a resource system in place so the deck building philosophy of Yu-Gi-Oh cannot be applied. Still my decks show results despite some of my friends who play the game questioning my deck building choices. For example me running Prohibition they find weird. Called By cannot stop Nibiru or Imperm so I run it as a counter along side Crossout. Odds are I have a counter to what my opponent is playing in my deck and even if I don’t I can still put them into a very tough spot. My extra deck is built for a one turn blowout. Either ending the match instantly or putting my opponent in a bind. Before Circular was banned the deck could stop a Dark Ruler with ease. Man I want circular back at 1 at the very least.

[@JessePerezStrategyGaming]

Wow yes! It seems you were using the EXACT thing i was trying to point out! You also supported your ignister engine with the mathmech one as additional utillity, built your deck to current local counters and did everything great! Shame what happened to circular :( On the deckbuilding side you get an A+! Now for the playing part practicing using new combos and finding a good replacement is probably the hard part. I think it was Bruce lee that said I fear not the man that learned 10000 punches but the man that practices 1 punch 10000 times.

[@dexslag]

i can see this applying to normal summons but if it can special itself from hand, it is immediately more valuable since your first starter is likely to get negated

[@JessePerezStrategyGaming]

If your first starter is negated and it is a HOPT then it doesn't matter if you can special summon another one of those copies because its a hard once per turn. If you mentioning "extenders" then your likely refering to decks that are 2 card combos who has math that is compeltely different from this video that i have in another video and you can find the 2 card "extender" math here. kzbin.info/www/bejne/moalkHZraKl0qpY When including extenders or cards that have 2 card combos the math to get the 85% range or to play around handtrap range for a 2 card combo the math becomes you want to run 20-23 starters.

I find that so interesting as well (ex. how to evaluate cards that are starters and also extenders, quantifying synergy between a card that works only with one card and where the combo is very linear vs a card that has multiple uses in the deck, etc.) I subbed because I think the math that you portray in your videos has been super useful to me, and I would love to see more of your content once you get to the really hard maths lol.

Yes & No at the same time - Like shordigers cat. It is both a normal summon and not because it can be ashed or bait an ash, at the same time - it also has utility purpose to thin the deck 1 draw & Prank kids full combo draws 2 during turn so that 1 mill is critical for better constancy for drawing into tech/handtraps. Therefore, yes it is a normal summon but you still would rather x3 field before x3 other pks names.

[@Alrange_5]

What about: non-normal summon starters, 2/3 card combos, free extenders (fenrir etc.), auxiliary engines (e.g. melodious), and starters that are also extenders (almost every card in a water xyz deck)?

[@JessePerezStrategyGaming]

I have a video on 2 card combos - for 2 card the math changes. You want to use about 20-23 "2 card starters" to have that 85% range.

I really like this deck building theory style type video! Though as some constructive criticism it's a bit slow to get started

[@gamerbg294]

One of these days, I was building a custom deck (with cards that would be flip monsters support), but the important thing is that my game plan didn't just depend on opening with 1 flip monster in my hand (1 flip monster could be a starter, but any other flip monster would become a combo extender), therefore, I decided to use a hypergeometric distribution calculator to evaluate the best combinations to have the greatest chances of getting 2-3 cards of a certain type in my hand and while experimenting with different combinations, I saw that a combination of 18 cards in a 42 card deck gives a very good chance of exactly having 2-3 cards (Incredibly, I already had this idea of not abusing 3-set cards, because in theory I could search any flip monster, so it would be better diversity for combo extension and in these 18 cards I don't use any 3-set cards, instead I use 6 2-set cards). Could you tell me if these numbers make any sense in practice?

Regarding Swordsoul: against which three-ofs would you actually advise? Triple Longyuan seems mandatory, either for an early Baronne (if she's legal) or to get draws with Qixing Longyuan. Going second, there are also other options such as Longyuan and Adhara to make Yazi which gets you to Tai A or Mo Ye. You'd also want to run at least two Ecclesiae (siding in a third one for going second) because while starting with her is weak to Ash, it's not _too_ bad (maybe Psy-Frame Gear Gamma is worth considering?) and she's also a free Tuner/non-Tuner if your opponent controls a monster. Mo Ye is the best Normal summon without any setup but there are many two card combos that let you start your plays without using your Normal summon immediately, in which case Tai A is just as good, if not better (Foolishly Burying a card may be better than drawing a random one). Emergence, too, is something you'd probably want to run at three because it's not just a starter but also a utility card, searching any Wyrm you want besides your starters (usually Protos). I suppose the Tenyi support spells should be at less than three, maybe two each (if you even run both). Adhara or Vishuda might be enough at two but Ashuna is certainly worth playing at three.

Prank Kids breaks this argument though, because the starters are also combo pieces. Maxing out on them doesn't necessarily hurt you outside of "starting" with Rocksies. 1 for 1 is not ONLY a start but also an extender. After any Prank Kids combo you thin the deck and are likely to draw non engine after from things like Pranks or Maxx C (master duel)

dose it make sense to run upstart in a deck bigger than 40, if you want to play more playsets? for a grind game or whatever?

[@JessePerezStrategyGaming]

For Mathimatical & Practical Purposes it can but there are very specific senarios where it is beneficial to do so. For example, a 41 card deck with the upstart is usually not smart unless the deck has quite a number of "bricks"/"garnets" where you would rather draw the upstart instead of the garnet, but a deck that is handtrap heavy the upstart could be a handtrap. So it is deck dependant.

[@Harmonic14]

​@@JessePerezStrategyGaming people used to play Upstart with more than 40 cards to have additional side out slots. There can be justifications for deck building that aren't strictly mathematical

[@JessePerezStrategyGaming]

@@Harmonic14 other reasons for upstart over 40 cards is also to mitigate the appearances of bricks. I have a video all on those reasonings including the one you mentioned in an upstart/pot video
