Blackwing - Aurora the Northern Lights

Cannot be Normal Summoned/Set. Must be Special Summoned (from your hand) by banishing 2 face-up monsters you control (1 "Blackwing" Tuner and 1 non-Tuner), and cannot be Special Summoned by other ways. Once per turn: You can banish 1 "Blackwing" Synchro Monster from your Extra Deck; until the End Phase, this card's name and original ATK become that monster's, and replace this effect with that monster's original effects.
