Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When your "Crystal Beast" monster is destroyed by battle: You can send 7 "Crystal Beast" cards with different names from your hand, Deck, and/or face-up field to the GY; Special Summon 1 "Ultimate Crystal" Fusion Monster from your Extra Deck. (This is treated as a Fusion Summon.) If a face-up "Ultimate Crystal" monster you control leaves the field because of an opponent's card effect: You can banish this card from your GY; place any number of "Crystal Beast" monsters from your GY, face-up in your Spell & Trap Zone as Continuous Spells.
