Because the permanent is on the battlefield both before and after it’s turned face up, turning a permanent face up doesn’t cause any enters-the-battlefield abilities to trigger.

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.

The creature spell is a 2/2 creature spell with ward {2} that has no name, mana cost, or creature types. The resulting creature is a 2/2 creature with ward {2} that has no name, mana cost, or creature types. Both the spell and the resulting creature are colorless and have a mana value of 0. Other effects that apply to the spell or creature can still grant it any characteristics it doesn’t have or change the characteristics it does have.

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.

Turning a permanent face up or face down doesn’t change whether that permanent is tapped or untapped.

If something tries to turn a face-down instant or sorcery card on the battlefield face up, reveal that card to show all players it’s an instant or sorcery card. The permanent remains on the battlefield face down. Abilities that trigger when a permanent turns face up won’t trigger, because even though you revealed the card, it never turned face up.

At any time, you can look at a face-down spell or permanent you control. You can’t look at face-down permanents or spells you don’t control unless an effect instructs or allows you to do so.

A permanent that turns face up or face down changes characteristics but is otherwise the same permanent. Spells and abilities that were targeting that permanent and Auras and Equipment that were attached to that permanent aren’t affected unless the new characteristics of the object change the legality of those targets or attachments.

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 face-down spell leaves the stack and goes to any zone other than the battlefield (if it was countered, for example), you must reveal it. Similarly, if a face-down permanent leaves the battlefield, you must reveal it. You must also reveal all face-down spells and permanents you control if you leave the game or the game ends.

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.
