Official rulings
The 8 most recent official rulings for Experiment Twelve, newest first.
A disguise ability lets you cast a card face down by paying {3} and announcing that you are using a disguise ability. Any time you have priority, you can turn a face-down permanent with disguise face up by paying its disguise cost.
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.
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.
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.
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.
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.
