Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 "Elemental HERO" monsters with different Attributes Must be Fusion Summoned. If this card is Special Summoned and your opponent controls more cards than you do: You can destroy all other cards on the field. You can Tribute this card that was Fusion Summoned using a Normal Monster as material, then target 1 "Elemental HERO" monster in your GY; Special Summon it. You can only use each effect of "Elemental HERO Thunder Giant - Voltic Thunder" once per turn.
