Faith Unbroken

• WWizards of the Coast2016-07-13
  Official Ruling
  The exiled card returns to the battlefield immediately after Faith Unbroken leaves the battlefield. Nothing happens between the two events, including state-based actions. However, if the creature Faith Unbroken enchants leaves the battlefield, Faith Unbroken won't leave itself until state-based actions are checked.

  Official Ruling
  In a multiplayer game, if Faith Unbroken's owner leaves the game, the exiled card will return to the battlefield. Because the one-shot effect that returns the card isn't an ability that goes on the stack, it won't cease to exist along with the leaving player's spells and abilities on the stack.

  Official Ruling
  If Faith Unbroken leaves the battlefield before its triggered ability resolves, the targeted creature won't be exiled.
