When an effect returns the exiled card â€œunder your control,â€ you control it indefinitely after that. In a multiplayer game, if a player leaves the game, all cards that player owns leave as well. If you leave the game, any creatures you control from Conjurerâ€™s Closet effect are exiled.
Once the exiled creature returns, itâ€™s considered a new object with no relation to the object that it was. Auras attached to the exiled creature will be put into their ownersâ€™ graveyards. Equipment attached to the exiled creature will become unattached and remain on the battlefield. Any counters on the exiled creature will cease to exist.
If you gain control of a creature â€œuntil end of turn,â€ you control it during that turnâ€™s end step.
If a token is exiled this way, it will cease to exist and wonâ€™t return to the battlefield.
