if an opponent activaters a card in response you can banish a card from your deck to negate the activation and destroy the card, or something like that. It can be used to even cancel nibiru.

if your enemy use ash blossom activate your crossout designator then banish ash blossom in your deck if you have one in your deck to negate the effect of your enemy ash blossom so if you have 1 copy of each OP cards like maxx c, ash blossom, infinite impermanence, solemn judgment, effect veiler, droll & lock bird you can negate all of them using crossout designator only if you have 1 copy of them each in your deck welcome :)

@@yowmamen6860 Pretty sure you can't chain to solemn, because they are counter cards
