Thygin, God of the Apocalypse

At the beginning of your upkeep, each
opponent loses X life and you scry X, where X
is the number of Nightmares 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 6/6 black Nightmare.
When Thygin dies, return her to her
owner's hand at the beginning of the next
end step.
