Settra, the Imperishable

At the beginning of your upkeep, each
opponent loses X life and you scry X, where X
is the number of Zombies you control.

{2}{u}{b}: Exile target creature card from a graveyard. Create a token that's a copy of it,
except it's a 4/4 black Zombie.

When Settra, the Imperishable dies, return it to its owner's hand at the beginning of the next end step.
