Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Each time an effect of a "Symphonic Warrior" card is activated, place 1 Symphonic Counter on this card when that effect resolves. All "Symphonic Warrior" monsters on the field gain 100 ATK for each Symphonic Counter on this card. Once per turn: You can remove 5 or 7 Symphonic Counters from your field; apply this effect, depending on the number of Symphonic Counters removed. ● 5: Inflict 300 damage to your opponent for each "Symphonic Warrior" card on the field. ● 7: Banish cards your opponent controls and/or in their GY, up to the number of "Symphonic Warrior" cards on the field.
