Bitter Work

Whenever you attack a player with one or more creatures with power 4 or greater, draw a card. Exhaust — 4: Infuse Stone 4. Activate only during your turn. (Target land you control becomes a 0/0 creature with haste that’s still a land. Put four +1/+1 counters on it. When it dies or is exiled, return it to the battlefield tapped. Activate each exhaust ability only once.){/color#ffffff}
