If a token is exiled this way, it will cease to exist and won't return to the battlefield.
Auron, Venerated Guardian
Once a creature is exiled by the reflexive triggered ability, it doesn't matter what happens to Auron's power. Reducing Auron's power below the exiled creature's power won't cause the exiled creature to return to the battlefield.
Auras attached to the exiled creature will be put into their owners' graveyards. Any Equipment will become unattached and remain on the battlefield. Any counters on the exiled creature will cease to exist. When the card returns to the battlefield, it will be a new object with no connection to the card that was exiled.
