Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can only control 1 "ZW - Pegasus Twin Saber". If your opponent's LP are at least 2000 higher than yours, you can Special Summon this card (from your hand). You can target 1 "Utopia" monster you control; equip this card you control to it as an Equip Spell that gives it 1000 ATK. Once per turn, while this card is equipped to a monster, you can negate a monster effect activated on your opponent's field.
