Face down cards are 2/1 Bird Illusion creatures
with flying. If a face down creature you control
dies, exile it instead. Give it flash, until end of
turn, you may cast it from exile without paying
its mana cost.
You may cast cards from your hand face down
for {x}, where X is its converted mana cost.
{4}: Turn a face up creature you control face
down.
