Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 Level 4 "Magician" Pendulum Monsters Must first be Xyz Summoned with the above Xyz Materials. Once per turn: You can detach 1 Xyz Material from this card; add to your hand, 1 DARK Spellcaster-Type monster from your Deck, Graveyard, or face-up from your Extra Deck. Once per turn, if a Pendulum Monster Card(s) in your Monster Zone or Pendulum Zone would be destroyed by battle or card effect, you can send 1 Spellcaster-Type monster from your Deck to the Graveyard instead.
