Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can activate 1 of these effects; ● Add 1 face-up "Solfachord" Pendulum Monster from your Extra Deck to your hand. ● Increase the Pendulum Scale of 1 "Solfachord" card in your Pendulum Zone by its Level this turn. ● If you control "Solfachord" Pendulum Monster Cards with at least 3 different even Pendulum Scales or at least 3 different odd Pendulum Scales, destroy 1 card your opponent controls. You can only use each effect of "Solfachord Harmonia" once per turn.
