Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When your opponent activates a monster effect on the field (Quick Effect): You can Special Summon this card from your hand, and if you do, send the top 3 cards of your Deck to the GY. If this card is sent to the GY by card effect (except during the Damage Step): You can Fusion Summon 1 Fusion Monster from your Extra Deck, by placing Fusion Materials mentioned on it from your hand, field, and/or GY, including this card from your GY, on the bottom of the Deck in any order. You can only use each effect of "Tearlaments Havnis" once per turn.
