Talk:Overturn Demon Lord, Asmodai/@comment-34817248-20180228092105/@comment-25709953-20180228152101

Looks like I need to step in not as a player but as an official (and verified) judge.

[Overturn], [Overkill], [Overthrow], and [Overkill REBoot] as an ability cannot be countered. What this means is that Overturn specifically cannot have anything responded to it. It is the final link in the chain, because you cannot add links once a chain starts to resolve (outside of Overturn/Overkill/etc.).

The scenario that has been presented can be confusing so let me break it down.

I declare an attack with Overturn Demon Lord, Asmodai, and during battle, I declare its Overturn. I choose Overturn Demon Lord, Asmodai as the target, and resolve the ability. It is still the attacking step and both players still have access to [Counter], because the step has not had both players pass priority then and neither player has used a counter. (For instance, my opponent may still cast a Blue Dragon Shield and I may still cast Abra Cadabra in response) Once both players declare they have nothing left to do, beginning with the turn player and ending with the non-turn player, then play proceeds to the next step. This is the key point here; declaring an Overturn (or such ability) doesn't negate the game rules of having to pass each individual step.

Just like Overturn/Overkill/etc. have to be declared properly within the game (see Heavenly Crystal Dragon, Aldo Athora and Overturn Knight, El Quixote for the two most misplayed Overturns in the game), they also don't negate entire steps. Even your Overturn Black Dragon, Abygale cannot stop an opponent's "at the beginning of your turn" effects from proccing and resolving.
