Malarok, Emaciated King

When Malarok, Emaciated King enters the battlefield, you become the monarch.
At the beginning of your upkeep, choose an
opponent at random. That player may sacrifice a creature. If they do, that player becomes the
monarch and you each draw a card.
At the beginning of your end step, if you became
the monarch this turn, create a 2/2 black zombie creature token for each opponent you have.
