Fusion Summon 1 Fairy Fusion Monster from your Extra Deck, using monsters from your hand, field, and/or Pendulum Zones. If a "Melodious" Fusion Monster(s) is sent to your GY while this card is in your GY, even during the Damage Step: You can place this card on the bottom of your Deck, then draw 1 card.
