3 rulings from Wizards of the Coast
- 26 July 2024If a token is exiled this way, it will cease to exist and won't return to the battlefield.
- 26 July 2024Once the exiled permanent returns, it's considered a new object with no relation to the object that it was. Auras attached to the exiled permanent will be put into their owners' graveyards. Equipment attached to the exiled permanent will become unattached and remain on the battlefield. Any counters on the exiled permanent will cease to exist.
- 26 July 2024Once a ward ability of another Frog has triggered, causing it to lose ward by removing Long River Lurker or changing its creature types won't affect that ability. The appropriate player will still have to pay {1} or have their spell or ability countered.
