Blackwing - Twin Shadow

Return 2 of your "Blackwing" monsters that are banished and/or in your GY to the Deck and/or Extra Deck (1 Tuner and 1 non-Tuner); Special Summon 1 "Blackwing" Synchro Monster or "Black-Winged Dragon" from your Extra Deck whose Level exactly equals the total Levels of those monsters. (This is treated as a Synchro Summon.) If you control 2 or more "Blackwing" monsters, you can activate this card from your hand. You can only activate 1 "Blackwing - Twin Shadow" per turn.
