Misophonia

Target creature gains haste until end of turn and attacks this turn if able.
Curse {4}{r}{r}: At the beginning of your end step, Misophonia deals 1 damage to you for each creature you control that did not attack this turn. (You may cast this spell for its curse cost instead of its normal cost. If you do, it enters the battlefield as an aura enchanting target treasure. Instead of its normal effect, apply its curse effect to the owner of the enchanted treasure.)
