Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can discard 1 Spell; add 1 LIGHT Ritual Monster or 1 Ritual Spell from your Deck to your hand. You can shuffle any number of Spells from your GY into the Deck, then target 1 LIGHT Fairy monster in your GY whose Level equals the number of cards you shuffled into the Deck; Special Summon it. You can only use each effect of "Ritual Sanctuary" once per turn.
