Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
3 Level 7 monsters Once per turn, if a "Kashtira Shangri-Ira" has activated its effect this turn, you can also Xyz Summon "Kashtira Arise-Heart" by using 1 "Kashtira" monster you control. (Transfer its materials to this card.) Any card sent to the GY is banished instead. Once per Chain, each time a card(s) is banished: Attach 1 banished card to this card as material. Once per turn (Quick Effect): You can detach 3 materials from this card, then target 1 card on the field; banish it face-down. * The above text is unofficial and describes the card's functionality in the OCG.
