Tsusamo, the Soul Warden

Whenever a spell or ability you control would
exile a nontoken, nonland permanent an opponent controls, you may pay 2 life. If you do, gain
control of that permanent instead of exiling it. (if
an affect says "exile until it leaves the battlefield," then
the owner would regain control of the permanent once
said permanent left the battlefield.)

and died, and all who ever will.
