Heretic, Unorthodoxy Risen

Double Strike

Nevermore - This creature deals combat damage to creatures, players, and planeswalkers in the form of Ruin counters. (A Ruin counter does absolutely nothing on its own.)

{5},{t}: Each creature, player, and planeswalker takes 2 damage for each Ruin counter it has, then remove all Ruin counters from those permanents.
