It would seem to quell rampant speculation for the Aesir Deck’s Link, Konami has clarified their intent.
Thor, Loki, and Odin once again descend upon the Dueling world! Boasting some of the highest ATK values among all Synchro Monsters, Team Ragnarok’s ace monsters from Yu-Gi-Oh! 5D’s hold a special place in the hearts of Duelists. Now, a new “Nordic” Link Monster makes it easier to assemble the Synchro Materials needed to Summon an “Aesir” monster, and this Deck’s Extra Deck also comes with more high-powered Level 10 Synchro Monsters, including the legendary Ascension Sky Dragon!
Specifically that the Aesir Deck comes with a “Nordic” Link Monster.
