Your opponent cannot activate a Spell/Trap Card, or monster effect, when your "Solfachord" Pendulum Monster(s) is Pendulum Summoned. Monster Effect
While you have an odd Pendulum Scale in your Pendulum Zone, if your "Solfachord" Pendulum Monster attacks, your opponent cannot activate Spell/Trap Cards or effects until the end of the Damage Step. During your Main Phase: You can Tribute 1 "Solfachord" Pendulum Monster (even if face-down), and if you do, Special Summon 1 "Solfachord" Pendulum Monster from your Deck whose Pendulum Scale is 2 higher or 2 lower than that monster, except "LaSolfachord Angelia". You can only use this effect of "LaSolfachord Angelia" once per turn.
