Alluring Blight

Blight costs {2} less to cast for each creature card in
any one opponent's graveyard.

At the beginning of each upkeep, that player may sacrifice a nontoken creature. If they do, they draw
two cards and lose 2 life.

Whenever an opponent sacrifices a creature, you may
pay 2 life. If you do, create an X/X green and black Zombie Saproling creature token, where X is that creature's toughness plus 1.
