Liliana, the Immortal

You may cast Zombie creature spells from
your graveyard once per turn.
Whenever a non-token creature you control dies, choose one:
• Gain 3 life.
• Draw a card, and discard a card. Lose 1 life.
• Create a 2/2 Black and White Zombie creature
token.
"So you've come to kill me, have you?
Well, you can try." - Liliana to Kaya
