Lysia's Absolution

Exile all creatures that all opponents control. If a creature exiled this way would return to the battlefield, tap it. It does not untap during its owner's next untap step. Deal 2 damage to each creature you control.
Lysia felt the light surging through her, waiting for her release. She let it go, and it brilliantly struck those who stood against her, melting them into oblivion.
