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}: 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.
