Garzogruthros Untamed

Indestructible, trample, haste
Whenever a creature an opponent controls deals
combat damage to you, put a bell counter on Garzogruthros. Then if Garzogruthros has three
or more bell counters on it, tap it. It doesn't
untap on your untap step.
At the beginning of your upkeep, remove a bell counter from Garzogruthros.
