Card Rulings:Solfachord Musica
- This card cannot be activated during the Damage Step.
- When activating this card, select which "●" effect to activate, and activate it as that effect. You can only select an "●" effect that meets its activation requirements based on the Pendulum Scales of the "Doremichord" Pendulum Monster Cards you control. (If you have both odd-numbered and even-numbered Pendulum Scales, you can activate any 1 of the effects.)
- The "● Odd and even" effect targets 1 card your opponent controls. (If you activate this effect, you also select a target at this time.)
