effects like {gift of immortality} or {Cloudshift} that exile or just return your cards to play from somewhere else do the creatures return the way they left or do they always return untapped? Because I've been playing gift as though the creature returns to play untapped
Or your opponent's running {Urabrask, the Hidden}.
Relevant rule:
