Fun control deck that can use the powerful Nordic Relic Svalinn to protect its floodgates or use it as powerful disruption while contently floating its high attack Aesir monsters until you run the opponent out of cards.
the core combo is:
open Alvis/ searcher for Alvis(foolish burial goods) + any nordic/searcher for a nordic
summon the nordic
link into Gullveig
activate Gullveig to banish Alvis to summon Ivaldi
chain 1 Alvis chain 2 Ivaldi
Ivaldi add Svalinn
Alvis send Ivaldi from field with Alvis and Valkyrie from deck to summon Odin
Keep in mind this isn't a combo deck and this combo and all the similar ones are set up so that you can stall into the late game.
