Mutate {3}{p/r}{p/g} (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, you may put a
land card from your hand onto the battlefield.
Morbid — First search your deck for a
basic land card and put it into your hand, then
shuffle your deck, if a creature has died this turn.
