Majin Buu

Trample

Whenever a creature dealt damage by Majin Buu
this turn dies, put a +1/+1 counter on Majin Buu,
then create a food token.

You may exert Majin Buu as he attacks. When you
do, sacrifice any amount of food tokens. Majin
Buu gets +X/+X where X is the amount of food
tokens sacrificed this way.
