Crow useless

You can only activate 1 "Mistaken Accusation" per turn

Its first effect can protect you from rogue burn strategies, and its second effect can defend you from battle damage in a pinch, but its third effect lets you banish it from the GY to add any other Performage from deck to hand

You can only activate this card when an Attack Position monster on your side of the field that inclues "Destiny Hero" in its card name is selected as an attack target
