Liliana's Virulence

Each opponent loses X life, you gain X life and draw X cards, where X is equal to the base loyalty of a black planeswalker in your graveyard. If X is five or more, return target creature with converted mana cost X or less from your
graveyard to the battlefield tapped.
"It isn't enough to simply live. To die is the greatest thrill imaginable."
