A magic judge could probably talk for 2 hours about the process of casting a spell aka playing a card. That game is wild. Yugioh has exactly one thing that's terribly complicated and unintuitive (the dmg step) everything else is fortunately relatively tame.

[@curo.]

Thank you so much for this. It's so hard to find detailed resources like this. I'd love a tutorial on how cards moving between zones changes interactions. Like you mentioned that a flip monster doesn't get its effect off if it is moved off the field before the effect resolves. Also I know there's interactions between things that negate a monster's effect, and that monster being sent to another zone and then still getting its effect off. Wording on specific cards like Effect Veiler, vs different wording on similar effects. All this could fit into the same lesson.

MAN EATER BUG was the beginning of this damage step battle phase shenanigans. I swear I see it starting from that flip effect where piercing damage still goes through if the duel is still going then a monster is destroyed and so many more substeps.

My opponent stopped me and said "Hayate is marked for destruction, it can't activate." I should have pushed back harder but during those weird discord yugioh times I didn't know how to summon a judge and just let it go. I lost the game after that. Wish I had this video back then.

Was hoping for information on the damage calculation prioritys in regards to things like Yubel and Nightmare Pain where you apply modifiers like double damage and reflecting ect. Solid presentation 👍

[@monkfishy6348]

Here's the order. 01: Inflicts double battle damage. 02: Battle damage is taken by both players. 03: Battle damage you take is also inflicted to your opponent / your opponent takes any battle damage you would take instead. (Apply either of these only once to each instance of damage). 04: Battle damage is treated as effect damage. 05: The player gains Life Points instead of taking battle damage. 06: Battle damage becomes 0. 07: Battle damage is halved. 08: Battle damage is doubled. 09: Battle damage becomes X (X being a predetermined value). 10: You do not take battle damage if it is more or less than X. (However, note that if the Battle Damage has become 0 when applying "06" effects, the remaining effects are not applied.)

@@fracazer Yeah this is a weird one. Just know that there's only 3 cards in the game that fall under category one. Blue-Eyes Chaos MAX Dragon, Silvera of the White Forest and Metalfoes Orichalc.

Also to note, all categories only apply once each, despite 03 specifying for itself. You can only halve any specific instance of damage once, double it once, etc.

[@jordaneworley]

@41:28 another good example is number 38 VS tenpai dragon chundra. If you attack with the tenpai, then number 38 can use its effect to redirect the attack to himself and your dragon cannot add to the chain because it’s not the “start” of the damage step anymore. Very dumb to find out mid-duel.

[@Venorpion]

PROFESSOR!!!! QUESTION!!!! Should we considered monsters "marked of destruction" equal as "destroyed but not sent to the GY yet" ???? Monsters like Revived King Ha des, Dark Ruler Ha Des or Ancient Gear Beast have effects that Negate the effects of monsters "destroyed by battle", even in the GY. Old players like myself remember that these monsters negate both Flip effects and sangan-like effects. So, the monsters being attacked would NEED to be considered "destroyed" for these negation effects to apply, right?

[@monkfishy6348]

A monster is considered "destroyed by battle" from the point Damage Calculation is performed. That is when the effects of Ancient Gear Beast etc... apply from.

[@SkyReaperOne]

Now we need another video deconstructing "things that can miss timing", "things that can't" and why the two are so different. (even though they literally aren't) GOD I hate this stupid ruling. IMHO, ALL card effect should be able to miss timing, or NONE of them should. And I know a lot of you will think: "Muhhhh! But the game is built around the fact that some things can and some things can't! It would make the game broken to change this!" Well, first off, the game's already a bloody mess to start with. And second, that does not invalidate the idea that this ruling is bad and dumb and should never have been a thing to start with. Or at the VERY LEAST, it should be made INCREDIBLY CLEAR what can and what can not miss timing. The difference should not literally be "One is ( : ) and the other is ( ; )". I can never even remember which is which!

[@emersongrtcg]

The difference, in fact, is pretty clear. Effects that can miss timing has their triggers written with a "When", as opposed to those which can't, wich start with a "If". At start, all effects are "When" effects, but Konami saw that this limits so much which effects can be created, so they create the "If". Nowadays, the "If" is the default. All effects that have a mechanical chance to miss timing starts with a "If" to guarantee that they will not. If you see a new card miss timing, be sure that Konami nerfed it on purpose.

[@SkyReaperOne]

@@emersongrtcg Ok, but can you explain to me why "when" misses timing and "if" doesn't? The two remain interchangeable and the only reason I know of to how they function is "because Konami said so", It is still very unclear and easy to mistake one for the other.

[@sidechannel5510]

@@SkyReaperOne How can you mistake them? They're different words.

[@SkyReaperOne]

@@sidechannel5510 You didn't answer my question though. How would little Timmy know which is which at a glance? There is no logical explanation to define why one is attributed to one word, while the other is attributed to the other. You're fine with it because you've been conditioned to it, and it stuck. Now it's no more then force of habit for you. Not because there's actually any rhyme or reason to it. Language exists to communicate things. When language is only used as a landmark, it has failed. If Yu-gi-Oh used keywords that were described in depth somewhere in a readilly available glossary, that'd be another thing, but we all know how much Konami fears stepping on MTG's toes about that.

[@monkfishy6348]

It can only be used at certain parts of the Damage Step, at the start and before damage calculation. Interestingly, if you activate it in the damage step and send the monster that is being attacked, the monster that was attacking that monster cannot attack again because damage calculation was reached. Neat little trick that can sometimes be relevant.

[@legromorph2854]

Very cool flavour coder as a teacher. Makes it much more enjoyable to watch. But I was wondering the whole time, why is purple poison magician mentioned in this ruling question.

While it should be able to, but on multifaker there is infact text that states: (except during the Damage Step) XD

[@JackYakumo]

So, I think there is an orden in which certain things are check during the damage calculation, thats why even if Yubel says that you take no damage from a battle, their spell can still reflect that damage. So maybe talking about that to complement this video would be good.

In the last, completely legal, activation of PPM scenario, would DNA Surgery/Transplant even matter?

[@monkfishy6348]

If a monster has an effect which activates just for being destroyed (by battle), it will still activate at the end of the damage step even if banished. Except if it's sent to the GY and then banished. Without seeing the exact game state or knowing the cards involved it's impossible to say.

[@Kintaku]

@ I wish I remembered the game. It’s on KZbin but I don’t remember which channel it was. There was a lot of debate about whether it was actually destroyed or banished first or whether the effect was supposed to resolve on field and thus didn’t because it was no longer “this card.” There was almost no consensus in the comment section and I couldn’t find any similar rulings that weren’t also able to be debunked at the time.

[@DistantCoder]

@@monkfishy6348that’s incorrect. if for example Baobaboon is attacked over with a zoodiax Xyz that has whiptail as marerial, even though the baobaboon is marked for destruction the effect of whiptail wil banish is after damage calculation. In this case the baobaboon is never destroyed by battle and therefore doesn’t activate.

[@monkfishy6348]

@@DistantCoder Well yeah, in that case it wouldn't because it was banished by an effect, not destroyed by battle (although it would be considered destroyed by battle if Ancient Gear Beast was applying from the point of damage calculation). But if a monster is *actually* destroyed by battle and it's banished instead of going to the GY at the end of the damage step, it will still activate.
