{5}{U}{U} Creature Leviathan 7/7 Mutate {5}{U} (If you cast this spell for its mutate cost, put it over or under target non-Human creature you own. They mutate into the creature on top plus all abilities from under it.) Whenever this creature mutates, tap up to X target creatures, where X is the number of times this creature has mutated. Those creatures don’t untap during their controller’s next untap step. Illustrated by Kev Walker Ikoria: Lair of Behemoths #283 EDHREC rank 9110 Magic: The Gathering, MTG
