Morph Morph is a static ability that functions any time you could play the card it's on, and the morph effect works any time the card is face down. "Morph [cost]" means "You may play this card as a 2/2 face-down creature, with no text, no name, no subtypes, no expansion symbol, and a mana cost of 0 by paying 3 rather than its mana cost." Any time you could play an instant, you may show all players the morph cost for any face-down permanent you control, pay that cost, then turn the permanent face up. This action does not use the stack. See rule 502.26, "Morph."
