Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 "Destiny HERO" monsters If this card is Special Summoned: You can target 1 Level 4 or lower "Destiny HERO" monster in your GY; inflict damage to your opponent equal to that target's ATK. If this card's current ATK is different from its original ATK (except during the Damage Step) (Quick Effect): You can target 1 card on the field; destroy it, and if you do, this card's ATK becomes equal to this card's original ATK. You can only use each effect of "Destiny HERO - Dystopia" once per turn.
