Bealzebufo, Devil Frog

Swampwalk
Kicker ({b/g}{b/g}{2})
If kicked, Bealzebufo enters the battlefield with 2
+1/+1 counters and fights target creature.
Mutate ({p/b}{p/g}{p/u}{4}): If you cast a Bealzebufo 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.
If Bealzebufo mutates destroy target creature and
gain life equal to its toughness.
