Shadows Tell No Lies

Shadow creatures you own that aren't on the
battlefield have Morph: {1}. (You may play those
cards as 2/2 creatures for {1}. Turn it face up any
time for its mana cost.)
You must reveal any Morph you play as you play
it.
Whenever you turn a card face up, each
opponent loses 1 life for each Shadow creature
you control.
