Menace

Mutate {3}{B}{B} (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.)

You may cast Anyibato, Death Refused from your graveyard using its mutate ability.

Whenever this creature mutates, each opponent sacrifices a creature. Put a +1/+1 counter on this creature for each creature sacrificed this way.
