Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
[ Pendulum Effect ] If you control no monsters, or only Pendulum Monsters, apply this effect, based on this card's Pendulum Zone. ● Left: Reduce its Pendulum Scale by 3. ● Right: Increase its Pendulum Scale by 4. During your opponent's Standby Phase: You can Special Summon this card. ---------------------------------------- [ Monster Effect ] If this card is Special Summoned to a zone that is not the center Main Monster Zone, destroy it. Cannot be destroyed by battle. Once per turn, during your opponent's End Phase: You can target 1 card in your Pendulum Zone; destroy it, and if you do, place this card in your Pendulum Zone.
