Laverra, Queen of Undeath

At the beginning of your upkeep, each opponent looses X life and you scry X cards, 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 Laverra dies, return her to her owner's
hand at the beginning of the next end step
