Any time you have priority, you may turn the face-down creature face up by revealing what its disguise cost is and paying that cost. This is a special action. It doesn’t use the stack and can’t be responded to. Only a face-down permanent can be turned face up this way; a face-down spell cannot.

If a face-down creature loses its abilities, it can’t be turned face up with a disguise ability because it will no longer have a disguise ability (or a disguise cost) once face up.

Because face-down creatures don’t have a name, they can’t have the same name as any other creature, even another face-down creature.

The face-down spell has no mana cost and a mana value of 0. When you cast a face-down spell, put it on the stack face down so no other player knows what it is, and pay {3} to cast it. This is an alternative cost.

If a spell or ability has damage divided, the division can’t be changed, although the targets receiving that damage still can. The same is true of spells and abilities that distribute counters.

If you choose new targets for a spell or ability, those new targets must be legal.
