5 rulings from Wizards of the Coast
- 9 February 2017If a token is exiled this way, it will cease to exist and won’t return to the battlefield.
- 9 February 2017Auras attached to the exiled permanent will be put into their owners’ graveyards. Any Equipment will become unattached and remain on the battlefield. Any counters on the exiled permanent will cease to exist.
- 9 February 2017The exiled card returns to the battlefield immediately after Thopter Arrest leaves the battlefield. Nothing happens between the two events, including state-based actions.
- 9 February 2017If Thopter Arrest leaves the battlefield before its triggered ability resolves, the target permanent won’t be exiled.
- 9 February 2017In a multiplayer game, if Thopter Arrest’s owner leaves the game, the exiled card will return to the battlefield. Because the one-shot effect that returns the card isn’t an ability that goes on the stack, it won’t cease to exist along with the leaving player’s spells and abilities on the stack.
