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.

The math might say one thing, but when I go into twelve straight games without drawing a starter, I start becoming suspicious of causality itself.

[@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.

[@JessePerezStrategyGaming]

[@neotemporal]

@@JessePerezStrategyGaming hey thanks for the thoughtful reply! no need to apologize, it definitely is hard to keep track of the banlists between 3 different formats. also w the imperm thing i see it as less of a correction and more just pointing it out so people in the comments are aware if they didnt see the other video; so no need to apologize there either:) glad to hear this didnt come off as a dig or anything, just wanted to point these things out as i think they’re important details. 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. Love the energy and keep up the good work :)

[@zoroarkon]

I would like to add to this that some cards are just better to draw than others in many situations and so are way better to draw 2 of than others that are different but are way less impactful.

One of my first decks I built for competitive was a hyper consistent Live Twins. I at first was frustrated with how all my opponents seemed to draw their nonengine against me while I kept flooding with normal summons and extenders until I realized I that i was causing myself this problem.

[@JessePerezStrategyGaming]

i too made that mistake with MANY of my decks for the longest time. it wasn't until way later i realized there is so much more a deck should do then try to turbo out 1 thing as close to 100% as possible.

[@Wyrmi]

@Wyrmi I didn't even stop there. I ran 2 of each costume Twin and a Home along on top of 3 Parallel Exceed. Half the deck was Starters or extenders.

[@sDkrumpedon]

Swordsoul is a 2-card combo deck, it needs to see a normal summon and a wyrm or swoso card. Traptrix is another deck that breaks the 8 playset rule because by design it can't combo with 1 card.

[@JessePerezStrategyGaming]

Yes! swordsoul is a 2 card combo! It has diffrent math you can find here kzbin.info/www/bejne/moalkHZraKl0qpY generally, for 2 card combos, you want to play 20-23 cards to be in that 85% range. Hopefully this helps

[@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

[@minepool4343]

That's what I thought as well

[@rhyned]

The prank kids example is also not good. Rocksies can banish card from hand, so 2 starters in hand is no problem.

[@jonathonyeary509]

@@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.

[@xCorvus7x]

The Prankids example is technically bad, too, because the deck Fusion summons, so it has use for more bodies in the hand, but the way it was described here focusing on the ratio of Normal summons, it works.

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

[@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. Thank you for this detailed comment, well put and well written. Thank you for watching!

[@Damini368]

I understand the point about 3x everything bad, but at the same time I want to add that just starting out learning a deck, it's great to see how things interact. Part of my process in learning a new deck is to start by playtesting three of each and scale back as I figure it out. As I start to see I don't want certain cards in hand as often I scale them back: I can search this card reliably, so I only need one or two; et cetera. It simultaneously builds knowledge of the deck and gives insight into numbers of copies.

[@hamedjabbari5883]

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.

[@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.

[@JessePerezStrategyGaming]

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.

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.

[@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

This video is wonderful, criminally underrated. Both easy and informative. I now actually know why it's wrong to run 3 sinful spoils and 3 poplar. Thank you❤❤

[@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.

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

[@Nomorehats]

This birthday paradox thing in yugioh could be a magnum opus or college thesis. You should definitely try to get this published maybe on YGOMeta This is definitely why I don't like 3 Dark Magical Circle in Duel Links Dark Magician Decks. Players will have 3 DM, 3 apprentice illusion, 3 navigation 3 rod and 3 circle in 20 card lists, where the odds are that circle will likely only reveal a duplicate copy of cards that are already in your hand. 2 is plenty

[@cinderefell1399]

Man, I just found this video/your channel, and I never been good at figuring out how to make decks. i always go blank. And it might be easy for a lot of people, but not everyone is a mathematician, right? Not everyone is good at deck building... But you're a great teacher.

[@JessePerezStrategyGaming]

Thank you! Comments like these really make my day!

[@MDagonic]

never thought about the playset thing. but after your video I checked my two recent decklists. somehow I did this 8 playset rule withouth knowing about it.

[@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

Nice, Im learning deckbuilding and this is valuable information. Thanks

[@Beiyuu]

I don't even play Yugioh, but you've opened my eyes

[@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.

[@forcommentingpurposesonly2918]

this video has conspiracy theory energy

[@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

[@melynx2399]

Hi, I discovered your channel yesterday and I find it very interesting ! I never thought about the probabilities behind deck building and relied on the belief to have a good list. Could you share the mathematical methods to obtain your stats/graphs? Because I think it could be interesting to teach to everyone the math behind their own decks! 🙏

[@JessePerezStrategyGaming]

hello! glad you find the channel helpful! The first thing is to use probability to determine your odds. Luckily science and math have advanced where there is calculators to do this for you if you don't know the math by hand. stattrek.com/online-calculator/hypergeometric This is a tool that you can use for basic probability calcs. Population size = deck size Number of successes in population = number of X Special cards your looking for Sample size = Hand Size Number of successes in sample = Number of X Special Cards you want in hand. That should be a good start! Let me know if that helps :)

[@adonaiblackwood7172]

You’re smart & great video! I have a similar methodology for my decks on Duel Links.

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]

[@seadnamaccasarlaigh279]

Hey, I love the idea of using the Birthday paradox to solve how many Playsets you want to run. Do you think you could go into more detail on how you calculated the 8 playsets or maybe a resource for how to calculate it When deck building? thanks!

[@Gredinus]

Would be really nice to have these recent videos for 60 card decks as well

[@thisisyanni8805]

Wow what a video! I have a question. I am playing Shining Sarcophagus with the horus engine and the only good normal summon you have is the gadget trio. The Future silence searches it.. The Sarcaphogaus also searches the gadget. How would you say shoild I pair it best with the horus engine. I am currently playing 3 droplets, 3 Fenrirs, 3 ash and imperm. I am thinking about cutting the ahs blossom and replacing it with the triple tactic talents. I hope you see this :)

[@LoneSWarrior]

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.

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. Some time i need tech card. But still didnt find the right one. Too much HT so bad. But less HT not good at all. I see your video about boardbreakers and i still think to put some on my deck.

[@JessePerezStrategyGaming]

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!

[@sergiocarrasco9762]

i love this channel and all its videos, even if I'm playing stun and most of the theory is hard to translate to such decks (what's an extender when your starters are floodgates like Pachycephalos?).

[@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.

[@zoominatii]

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

[@ThatsSoGiorgio]

I’m playing 50 Branded. I believe I have no more than 4-5 Playsets (Albaz, Fusion, Albion, Aluber) I have a few down to 2 because I do not want to draw too many of them but I have a ton of 2 ofs like Allure, Fusion Deployment and I also run Pot of Desires. By the time I comb off turn one, I’m down to 20 cards or less after interruption.

[@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

[@lucanalon1576]

@@JessePerezStrategyGaming kzbin.info/www/bejne/kGGbl6ysjdV6i6ssi=KpuZPUJZJkiJzGW6 This was the format, oc played in a casual way. But this proves the preconseption you were adressing in your video: the avarage yugioh player doesn't understand what odds are

[@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.

[@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

[@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!

[@Deception975]

In all the years I've played Yu-Gi-Oh, I've never really come across a video like this. It's kind of weird now that I think about. I have played MTG for longer, though. Which I have a deck building mindset from that. So, I would just build decks, play test, and make adjustments if needed. I guess I'm just somewhat acknowledging stuff I didn't know that I knew. Or rather, barely thought about, again from having the MTG background. All in all, just saying this video is neat.

[@TheAz0680]

I would love to see how this math applies in branded, you have in a 40 build 3 of aluber, albaz, deployment, fusion, opening and sometimes nadir and SOMEHOW, i never saw a branded player brick in any way

[@drmuffinx233]

The ace attorney theme goes well with ur vids, if you make it a staple for your vids it’ll be amazing

[@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?

[@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.

[@Srusso1004]

You are a genius! Now I can laugh at my foes from the rooftops of my masters ranking.

[@Casper-jx3vv]

Snake eye casually playing 18 hand traps and starters

[@styxxiii]

I need to learn how you do the math on this. I can't figure out a good RDA ratio.

[@VORTEX___]

A counter argument example would be superheavy samurais. the deck ran 12 starters in 40 in a handtrap format and bricked too much. running 15ish starters would have been much better. in around 25 games, you bricked around 4 games. You also definitely want enough extenders to push through.

[@JessePerezStrategyGaming]

Superheavy samurai while some cards are a 1 card combo - most others are 2 card combos (they have to equip or need another on board). In 2 card combos the optimal ratios are running 20-23 cards to facilitate that. I should have put that in this video but I fear it was getting to long as it is. I have the math for 2 card combos here: kzbin.info/www/bejne/moalkHZraKl0qpY But yes your conclusion is correct. For something like super heavy I would even take it a step further and run 20-23 of them to facilitate their 2 card combo strategy instead of 15 and consider the 1 card combo/starters more of a luck. Thats what the math shows for them to have that 85% area and not be hyperconsistant. Also SH isn't limited to the 1 normal summon for the most part like the prank kids. Since they have sooo many extenders that can special themselves playing through the handtraps is very important and getting the extenders by playing the 2 card combo ratios 20-23 will allow to play through an extender. TLDR: You are correct a deck like superheavy should be playing more than the 12 starters and should be playing an upwards of 20-23 SH cards that can facilitate their plays.

[@autobotstarscream765]

15 sounds like the ideal number in 40-card, it's been working great for Tenpai.

[@YamiVT]

The deckbuilding hero we deserve

[@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.

[@user-dg8uv4oz5z]

This equation seems really interesting. Would it be able to do a DL variant of this with the variables 20 Main Deck and 4 cards in hand. What would be the optimal Ratio for Starters so that you don’t oversaturate

[@nook9871]

Can you do a vid on 2 card starters? i run unchained and i want to know how many of the S/T i should run along with aruha/sharvara

[@xCorvus7x]

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.

[@harleypettersen9225]

crazy how you can have a base premise thats pretty good then have absolutely 0 good reasoning for it and get everything else completely wrong goddamn

[@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]

This is a good video to show to people begging for more Photon Galaxy starters when the Deck already has about 10-11. The Deck is consistent enough. 3 Galaxy Wizard 3 Galaxy Soldier 3 Galaxy Hundred 1 Foolish Burial 2 Photon Delta Wing The Deck hit that sweet spot long ago. Begging for more starters is going to give Photon Galaxy diminishing returns. At this point, what the Deck needs is a better grind game.
