Optical Illusion

Morph {3}{g/w}{g/w} (You may cast this card from your hand for {3}. Then, turn it face up anytime for its morph cost.)
When Optical Illusion enters the battlefield or is turned face up, you may reveal a permanent from your hand. For as long as you control Optical Illusion, target nonland permanent loses all abilities and becomes a copy of the revealed card.
"Whoa! Now I see it!"
