2017-02-09: If a creature token is exiled this way, it will cease to exist and will not return to the battlefield.

2017-02-09: After the permanent returns to the battlefield, it will be a new object with no connection to the permanent that was exiled. It won’t have any additional abilities it may have had when it was exiled. Any +1/+1 counters on it or Auras attached to it are removed, and any Equipment will no longer be attached.
