Leah, Vessel of Terror

Whenever you are attacked by one or more creatures an opponent controls, discard a card and put a Terror counter on Leah.

At the beginning of your end step, remove all Terror counters from Leah. Leah does that much damage to each opponent. If you have no cards in hand, exile a nonland card from your graveyard. Add an amount of {b} or {r} in any combination equal to that cards mana value.
