2 rulings from Wizards of the Coast
- 12 April 2024If the Aura you control becomes unattached from a nonland permanent (most likely because the Aura left the battlefield) before Eriette’s triggered ability resolves, you won’t gain control of that nonland permanent at all.
- 12 April 2024If the mana cost of a permanent includes {X}, X is 0 for the purpose of determining its mana value.
