Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 Warrior monsters with different Attributes Once per turn, when a card or effect is activated that targets this card (Quick Effect): You can negate that effect, and if you do, destroy 1 card on the field. If this card was Fusion Summoned using only monsters on the field as material, it can make a second attack during each Battle Phase. Once per turn, if this card battles an opponent's monster, during damage calculation (Quick Effect): You can banish 1 Spell from your GY; this card gains ATK equal to half its current DEF, until the end of this turn.
