Monster Ally — 7/4 Colossus — Play Cost: 6
If this ally would be destroyed, remove all damage from it, exhaust it, and add three stone counters to it instead.
At the start of your turn, remove a stone counter from this ally. If none remain, ready this ally.
While this ally has a stone counter on it, it can't ready and has Invincible.
