Kibo, Uktabi Prince

{t}Each player creates a colorless artifact token:

Banana: "{t}, Sacrifice this artifact:
Add {r} or {g}. You gain 2 life.”

Whenever an artifact an opponent controls is put into a graveyard from the battlefield, put a +1/+1 counter on each Ape/Monkey you control.

Whenever Kibo attacks, defending player sacrifices an artifact.
