Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If this card is sent to the GY as material for a Fusion Summon: You can Set 1 "Dracotail" Spell/Trap from your Deck, then you can destroy 1 monster on the field. If a face-up Fusion Monster(s) you control is destroyed by an opponent's card effect, while this card is in your GY (except during the Damage Step): You can place this card on the bottom of your Deck, and if you do, Special Summon 1 non-Fusion "Dracotail" monster from your GY. You can only use each effect of "Dracotail Pan" once per turn.
