Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Your opponent cannot activate cards or effects when you Normal Summon a FIRE Warrior monster. Once per turn: You can send 1 monster from your hand or face-up field to the GY; Special Summon 1 "Flame Swordsman" from your Extra Deck. (This is treated as a Fusion Summon.) Once per turn, when a monster declares an attack: You can target 1 Warrior monster you control; until the end of this turn, it loses exactly 1000 ATK, but all other monsters you currently control gain 1000 ATK.
