Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If you control a Continuous Spell: You can Special Summon this card from your hand. If this card is Special Summoned from the hand: You can send 1 Level 4 or lower LIGHT Spellcaster monster from your Deck to the GY. If this face-up card leaves the field: You can target 1 Spell/Trap on the field; destroy it. You can only use each effect of "Performapal Sky Magician Girl" once per turn.
