Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
During your Main Phase: You can destroy 1 card in your hand, and if you do, Special Summon 1 Level 4 or lower "Nephthys" monster from your hand, except "Defender of Nephthys". During your next Standby Phase after this card was destroyed by card effect and sent to the GY: You can destroy 1 "Nephthys" monster in your Deck, except "Defender of Nephthys". You can only use each effect of "Defender of Nephthys" once per turn.
