GORA

GORA can't attack or block unless it has three
or more pillar counters on it.
When a creature an opponent controls with a converted mana cost of 3 or more is sent to the graveyard or exiled from the battlefield, put a
pillar counter on GORA.
Whenever GORA has five or more pillar
counters on it, you win the game.
It cannot be stopped once unsealed. The Pillars are
the only ones that can contain it.
