Enchanted creature gets +1/+1 and has vigilance.
When enchanted creature dies, manifest the top card of your library. (Put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)

Any time you have priority, you may turn a manifested creature face up by revealing that it’s a creature card (ignoring any type-changing effects that might be applying to it) and paying its mana cost. This is a special action. It doesn’t use the stack and can’t be responded to.

If a face-down permanent you control 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 if the game ends.

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

The face-down characteristics of a permanent are copiable values. If another object becomes a copy of a face-down creature or if a token is created that’s a copy of a face-down creature, that new object is a 2/2 colorless face-up creature with no abilities.
