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.
