The Head of Pookie

Mutate {1}{w}{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.)
When this creature enters the battlefield or
mutates, scry X where X is it's power, then
draw a card.
At the beginning of your end step, if you control
a Bro creature with 4 mutations and "Literally
The Greatest" you win the game.
