Svetian, Voice of the Aria

Lifelink
{x}{w},{t}: Prevent the next X damage dealt to target creature you control. Svetian deals damage equal to the damage prevented this way to that creature. If it dies this way, exile it instead.
When a card an opponent controls is exiled, put a +1/+1 counter on Svetian.
"The Aria shall purify this world. I'll see to that."
