MAGIC: THE GATHERING
Punishing Fire deals 2 damage to any target.
Whenever an opponent gains life, you may pay . If you do, return Punishing Fire from your graveyard to your hand.
This burn spell is part of such a powerful combo that it was banned in Modern. In case you haven't seen it before, tapping Grove of the Burnwillows for red mana makes your opponent gain life, which returns your Punishing Fire. Creature decks don't stand a chance.
