Krang & Shredder (Showcase) (TMT-245) - Teenage Mutant Ninja Turtles

Whenever Krang & Shredder enter or attack, each opponent exiles cards from the top of their library until they exile a nonland card.

Disappear — At the beginning of your end step, if a permanent left the battlefield under your control this turn, you may cast a card exiled with Krang & Shredder without paying its mana cost.
