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.

This is awesome. We needed this!!

[@ggpt9641]

Wow. Learning about MD's display of the 5 damage steps in combat is definitely useful information. It also just hit me that I can make notes right here. Phases of combat: Beginning > Battle > Damage (5 sub-steps total). 7 types of effects can be used during the damage step: 1:Mandatory, 2:Counter traps (the ones with the arrows), 3:fast effects that negate an activation (different than negating an effect, which is why you lose to Chundra despite having an Ash Blossom, AB negates the effect and not the activation. If I'm not mistaken then, if you had 0 monsters you could Psyframe Gamma here as risky as that is). 4: Effects that specify activation in the damage step. 5: Cards that can be activated during the damage step. 6: Triggers when the card (often a monster) is moved. Professor Coder mentions a difference between cards that say "when another card goes to the (zone) , do X" and "When THIS card goes to the (zone), do X". The latter works but not the former. 7: Fast effects that modify ATK/DEF.* 5 steps of the damage step: Start > before damage calculation > during/perform damage calc > after D. calc > end. Notably to me, step 2 is the last chance to modify ATK/DEF. The monster is flipped but no flip effects at this time. Step 3 can use relevant fast effects EXCEPT modify ATK/DEF. A losing monster is also marked for destruction (if relevant) and that monster isn't destroyed yet, but cannot be: targeted, returned to hand/deck, be used for optional costs, nor have: position, control, continuous effects or optional fast effects applied. That monster can be: destroyed/banished/ by effects and pay mandatory costs (if the phrase "you may" is absent, this seems like a good indicator of mandatory), have its effects negated, apply unclassified effects, mandatory fast effect, and flip/trigger effects. 1 more personal note about step 5: Bystial Druiswurm triggers on step 5 if destroyed by battle. Battle calculation is the final step of step 3 in which damage is dealt and marked for destruction occur. This step must be done for monsters to be treated as "battled." (Zeus summoners!)

[@lordeng1ish]

Man, I learned so much. I just this week learned about steps 1 and 2 because I tried to set a Chundra. Back in Dino Rabbit days I also learned (now I learn incorrectly) that "negate the activation and destroy" are the type of effects that can be activated during the damage step. Also back in the day people tried to pull some shit with what is and isn't allowed with honest and bujingi crane. Bullshit about only one chain, forcing the opponent into an avramax situation with honests. Now I know. Thank you Mr. Coder.

[@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.

I got screwed a few years ago during the remote duel era in one of the official tournaments. My opponent attacked my Hayate and I declared it's effect, knowing I could send Raye, trigger Raye to summon and then snowball from there. 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.)

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?

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.

How does a card like Tindangle Angel apply its effect? When it summon a Flip monster and ends the battle phase does it just skip the rest of the Damage Step sub-steps entirely? Do cards like Evenly Match have a chance to apply when that battle phase is ended? As well I now know why Tindangle Intruder has a MANDATORY effect to summon itself when a monster is summoned in face-down defence, its so it can trigger during the damage step and work with angel! Now that I think about it its odd that Tindangle Trinity's effect protects itself while BAs don't die upon being immediately flipped...

So, if I'm understanding this right... if you have a set Tour Guide, for example, and a face-up BA monster. The opponent attacks into Tour Guide, flipping it up. During substep 4, the BA monster kills itself even though the Tour Guide is marked for destruction? I know he did this example with Fiendish Rhino Warrior, but that was more to illustrate the "continuous effects don't apply" side.

[@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. Is this the kind of stuff coder did to dzeff with altergeist rulings. Asking if multifaker can acrivate in Damage Step. While it should be able to, but on multifaker there is infact text that states: (except during the Damage Step) XD

[@Kintaku]

20:30 I wonder if this explains an interaction that was saw a few months ago (I think it was with Farfa) where a monster had an effect if destroyed but it was banished and didn’t proc. The card was cracked so everyone thought it was destroyed so no one could figure out what went wrong.

[@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. I guess I should have looked at the linked part of the video to get a fuller context.
