Cultleader Supreme

Enslaver (If a creature dealt damage by this creature this turn would die, you gain control of it instead for as long as you control this creature.)
At the beginning of each player's upkeep, for each creature that player owns but doesn't control that player may pay 5 life. If they do, they gain control of that creature.
I will gaze only in darkness and fear the light...
