True Identity

A disguise ability lets you cast a card face down by paying 3 generic mana 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.

The creature spell is a 2/2 creature spell with ward 2 generic mana that has no name, mana cost, or creature types. The resulting creature is a 2/2 creature with ward 2 generic mana 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.

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