Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If only this card is banished by the effect of a "Nordic" Link Monster: You can send to the GY, 1 "Nordic" monster you control and 2 "Nordic" monsters from your Deck, whose total Levels equal 10, then Special Summon 1 "Aesir" monster from your Extra Deck. If an "Aesir" monster(s) in your possession is sent to your GY by your opponent, except by battle: You can banish this card from your GY; Special Summon 1 "Aesir" monster from your Extra Deck, with a different name from the cards in your GY. You can only use this effect of "Alviss of the Nordic Alfar" once per Duel. * The above text is unofficial and describes the card's functionality in the OCG.
