Bashful Beastie

To manifest dread, look at the top two cards of your library. Manifest one (by putting it onto the battlefield face down) and put the other into your graveyard. The card you put onto the battlefield becomes a 2/2 face-down creature with no name, mana cost, creature types, or abilities. It's colorless and has a mana value of 0. Other effects that apply to the permanent 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.

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