Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
"Reign-Beaux, Overlord of Dark World" + 2+ Fiend monsters If this card is Fusion Summoned: You can destroy all cards your opponent controls. This card's original ATK/DEF each become the number of materials used for its Summon x 1000. Once per turn (Quick Effect): You can target 1 face-up card you control; discard 1 card, also your opponent cannot target that face-up card with card effects for the rest of this turn.
