Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Target 1 "Utopia" monster you control; Special Summon from your Extra Deck, 1 "Utopia" monster with a lower Rank than that monster you control, by using it as the Xyz Material. (This Special Summon is treated as an Xyz Summon. Xyz Materials attached to it also become Xyz Materials on the Summoned monster.) The monster Xyz Summoned by this effect gains this effect. ● If this card attacks, or is attacked by, an opponent's monster, the opponent's monster's effects are negated during the Battle Phase only.
