Demonic Scroll

Morph—Sacrifice a creature. (You may cast this
card face down as a 2/2 creature for {3}. Turn it face
up any time for its morph cost.)
When Demonic Scroll is turned face up, create
an X/X black Demon creature token with flying,
where X is the number of cards in your hand.
{2}{b}, {t}: You draw a card and you lose 1 life.
