6 rulings from Wizards of the Coast
- 9 September 2022In a multiplayer game, if Leyline Binding'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.
- 9 September 2022If Leyline Binding leaves the battlefield before its enters-the-battlefield ability resolves, the target permanent won't be exiled.
- 9 September 2022Auras attached to the exiled permanent will be put into their owners' graveyards. Equipment attached to an exiled creature will become unattached and remain on the battlefield. Any counters on the exiled permanent will cease to exist.
- 9 September 2022Leyline Binding's last ability is a single ability that creates two one-shot effects: one that exiles the permanent when the ability resolves, and another that returns the exiled card to the battlefield immediately after Leyline Binding leaves the battlefield.
- 9 September 2022If a token is exiled, it ceases to exist. It won't be returned to the battlefield.
- 12 April 2024Leyline Binding's domain ability doesn't change its mana value, which is always 6.
