Auras attached to the exiled creature will be put into their owners' 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. Once the exiled creature returns, it's considered a new object with no relation to the object that it was.

Charming Prince's third mode can target any creature you own, including those another player controls.

If a token is exiled this way, it will cease to exist and won't return to the battlefield.
