What are the official rulings for Eriette, the Beguiler?
user
0. If 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.
1. If the mana cost of a permanent includes {X}, X is 0 for the purpose of determining its mana value.
