Slumbering Thoctar

Trample
Whenever a creature you control with a +1/+1 counter on it deals combat damage to a player, you may pay {r}{g}{w}. If you do, return Slumbering Thoctar from your graveyard to your hand.
Reinforce 3- {2}{r/w}{g} ({2}{r/w}{g}, Discard this card: Put 3 +1/+1 counters on target creature.)
