Face down cards are 2/1 Bird Illusion creatures.
If a face down creature you control dies, exile
it instead. 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 - 1.
{4}: Turn a face up creature you control face
down.
