Wesley, the Zombie God

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 Wesley, the Zombie God dies, return it to
its owner's hand at the beginning of the
next end step.
