Silkwrap

Face-down creatures have a mana value of 0. If one is exiled by Silkwrap, it will return to the battlefield face up.

Silkwrap's ability causes a zone change with a duration, a style of ability that's somewhat reminiscent of older cards like Oblivion Ring. However, unlike Oblivion Ring, cards like Silkwrap have a single ability that creates two one-shot effects: one that exiles the creature when the ability resolves, and another that returns the exiled card to the battlefield immediately after Silkwrap leaves the battlefield.

The exiled card returns to the battlefield immediately after Silkwrap leaves the battlefield. Nothing happens between the two events, including state-based actions.
