You may cast creature cards face down for X,
where X is it's converted mana cost - 1.
Face down creatures are 2/1 Illusions.
If a face down creature dies, create a face up
token copy of it. If it had an effect that would
trigger upon turning face up, it does.
{4}: Turn a face up creature you control face
down.
