"Solfachord Scale" Rating Score by とき

A card that can use various effects depending on the number of Solfachord monsters on the field.
With 3 types or more, the effect of returning a card from the P zone to the hand and instead placing his face-up Solfachord in the EX Deck into the P zone, 5 types or more with the effect of special summoning 1 of his Solfachord from the hand, 7 types It has the effect of destroying all face-up cards of the opponent.
I don't think it's possible to have 7 types when the field is limited to 5, but he in the P zone counts Solfachord, so that's a maximum of 7 types.
Three types of effects change the arrangement of P monsters. It will probably be when you want to use the Courier or Cutia on the scale, but considering the weight of the conditions, it's not a very useful effect. The 5 types of effects are Special Summons from your hand, but if you can use this effect, you will have at most 3 of his Solfachords on the field. In that case, the P-summoning system will be in place, and I don't really know what card I want to target with this card instead of P-summoning.
7 types are Roman cannons. Do not touch the back side. If you can clear the field, you will definitely win, but...
The three types of effects can be activated in combination, but the directionality is difficult and even if they are used separately, the combo effect is poor. I feel like the benefits don't match the hard work.
