Donkey Kong

{t} Each player creates a colorless artifact
token named Banana with "{t}, Sacrifice this
artifact: Add {r} or {g}, You gain 2 life."
Whenever an artifact an opponent controls
is put into graveyard from the battlefield, put
a +1/+1 counter on each creature you control
that's an Ape or a Monkey.
Whenever Donkey Kong attacks, defending
