The Legs of Pookie

Mutate {3}, Kicker {w} and/or {u} (You may pay
an additional {w} and/or {u} as you cast this spell.)
When The Legs of Pookie enters the battlefield,
exile another target nonland permanent for each
time it was kicked. Whenever this creature
mutates, you may exile another target nonland
permanent. Return those permanents to the
battlefield under their owner's control at the
beginning of the next end step.
