Emberclaw, Pyroforge Overlord

Haste, Menace
Whenever Emberclaw, Pyroforge Overlord deals combat damage to a player, you may sacrifice a creature. If you do, Emberclaw deals damage equal to the sacrificed creature's power to any target.
At the beginning of your end step, if you control three or more creatures that dealt combat damage this turn, you may return a creature card from your graveyard to the battlefield.
"From the fires of battle, Emberclaw forges an army reborn in the crucible of conflict."
