King of Thralls

When a permanent an opponent owns is put in a graveyard of exile, put it onto the battlefield
under your control unless that player pays life
equal to that cards converted mana cost plus 2.
If you control four or more permanents you
don't own, when King of Thralls deals combat
damage to a player, you may destroy target
creature.
