Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can activate this card when an opponent's monster declares a direct attack. When this card's activation resolves, negate the attack, then Special Summon this card as an Effect Monster (Fiend/LIGHT/Level 1/ATK 0/DEF 0). (This card is also still a Trap Card.) During your Standby Phase, while this card is treated as a monster: You can banish any number of "Utopia" monsters with different names from your GY; inflict 500 damage to your opponent for each of those banished monsters, and if you do, this card gains ATK equal to the damage they took. * The above text is unofficial and describes the card's functionality in the OCG.
