Sylvanas, The Banshee Queen

Reach, Deathtouch

Whenever a nontoken creature dies during your turn, create a black Zombie creature token. Its power is equal to that card’s power and its toughness is equal to that card’s toughness.

When Sylvanas dies, you may sacrifice a nontoken creature. If you do, return her from the graveyard to the battlefield tapped at the beginning of the next end step.

"I will grow the ranks of the Forsaken. One
way... or another."
