Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 Level 3 monsters Neither player can target this card on the field with card effects. If this card would be destroyed by battle or card effect, you can detach 1 material from this card instead. Once per turn, during your Standby Phase: Gain 500 LP. If this card is sent from the field to the GY: Target 2 Level 3 monsters in your GY; shuffle them both into the Deck, and if you do, return this card from your GY to the Extra Deck. You can only use this effect of "Number 49: Fortune Tune" once per turn.
