While you have a "Solfachord" card(s) in your Pendulum Zone, when your opponent activates a Spell/Trap Card, or monster effect: Shuffle 1 face-up Pendulum Monster from your Extra Deck into the Deck, then apply these effects.
●Pendulum Monsters you control are unaffected by that effect.
●Cards in your Pendulum Zone cannot be destroyed by that effect.
●Cards in your Pendulum Zone cannot be banished by that effect.
You can only activate 1 "Solfachord Formal" per turn.
