Marcus Licinius Crassus

Extort (Whenever you cast a spell, you may pay {w/b}. If you do, each opponent loses 1 life and you
gain that much life.)
Whenever a land enters the battlefield under an opponent's control, that player may pay {2}. If
the player doesn't, you create a Treasure token.
Sacrifice five Treasures: Gain control of target artifact or land an opponent controls for as long
as you control Crassus.
