Chromastone

{1},{t}: Remove any number of Crystal counters from Chromastone.
Put a Crystal counter on this creature for each damage it takes in combat.
When this creature has counters removed, deal that much damage to target creature.
You may redirect damage to Chromastone instead of target creature you control.
If Chromastone is put in a graveyard, remove all counters attached to it.
