Pingstorm

When Pingstorm enters the battlefield, exile all instant and sorcery cards from all graveyards. Put
X charge counters on Pingstorm where X is equal to the number of cards exiled this way. When it has no charge counters on it, sacrifice Pingstorm.
Whenever a player casts a spell, Pingstorm deals 1 damage to that player. Remove a charge counter from Pingstorm. If that spell was a creature spell, Pingstorm deals 1 damage to that creature as well.
