The Scarab 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}{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 The Scarab God dies, return it to its owner's hand at the beginning of the next
end step.
