4 rulings from Wizards of the Coast
- 25 January 2019The creature returns untapped unless another effect causes it to enter the battlefield tapped.
- 25 January 2019If a token is exiled this way, it will cease to exist and won’t return to the battlefield.
- 25 January 2019The returned card won’t be the target of any spells or abilities that targeted it before. Spells that don’t target, such as Kaya’s Wrath, may still affect it.
- 25 January 2019Once the exiled creature returns, it’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 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.
