6 rulings from Wizards of the Coast
- 25 July 2025If an artifact or creature has {X} in its mana cost, X is 0 for the purpose of determining its mana value.
- 25 July 2025Every token has mana value 0 unless it is copying something or was created with a specific mana cost.
- 25 July 2025In a multiplayer game, if Pinnacle Starcage’s owner leaves the game, the exiled cards will return to the battlefield. Because the one-shot effect that returns the cards 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.
- 25 July 2025Auras attached to an exiled permanent will be put into their owners’ graveyards. Equipment attached to an exiled permanent (if they’re not also being exiled) will become unattached and remain on the battlefield. Any counters on the exiled permanents will cease to exist.
- 25 July 2025If Pinnacle Starcage leaves the battlefield before its first ability resolves, no artifacts or creatures will be exiled.
- 25 July 2025If a token is exiled this way, it will cease to exist and won’t return to the battlefield.
