Vanille, Cheerful l'Cie

When Vanille enters, mill two cards, then return a permanent card from your graveyard to your hand. At the beginning of your first main phase, if you both own and control Vanille and a creature named Fang, Fearless l'Cie, you may pay {3}{B}{G}. If you do, exile them, then meld them into Ragnarok, Divine Deliverance.
