Special Summon in Defense Position, 1 “Blue-Eyes” monster from your Deck, GY, or banishment (but if you control no “Blue-Eyes White Dragon”, you can only Special Summon “Blue-Eyes White Dragon” with this effect), also you cannot Special Summon from the Extra Deck for the rest of this turn, except Dragon monsters. You can banish this card from your GY; Fusion Summon 1 Fusion Monster from your Extra Deck, using monsters from your hand or field, including a “Blue-Eyes” monster.
