"Nordic Ascendant", known as "Polar Star Angel" (極星天Kyokuseiten) in the OCG and the Japanese anime, are a sub-archetype of the Nordic cards. They are a group of Fairy-typemonsters used by Halldor in the Yu-Gi-Oh! 5D's anime. Except for "Vanadis of the Nordic Ascendant", whose name is an alternative name of the Norse Goddess Freyja, the other two members of this archetype are based on Norse Mythology figures associated with Odin. "Mimir" is the name of a Norse God renowned for his wisdom and knowledge, who is the guard of the Well of Wisdom and Insight, where one of the roots of the tree Yggdrasil concludes. Into his well, Odin cast his eye to gain knowledge of the future. "Valkyries" are a host of female figures who serve under Odin, and decide who will die in battle. They are also responsible for bringing the dead warriors to the afterlife, into the Halls of Valhalla (where they become Einherjars), that is ruled by Odin himself.
"Nordic Ascendants", like "Nordic Beasts" and "Nordic Alfar" focus on quickly getting out their "Aesir" Synchro Monster "Odin, Father of the Aesir" out as soon as possible to punish the opponent. With this, you would require to have quite a few cards to focus on bringing out the tuners as soon as possible in order to carry this task out before the opponent manages to create a field advantage. One of the main weaknesses of "Odin" is "Bottomless Trap Hole", thus you will need protection. Here is an example of cards which would go well in a "Nordic Ascendant" Deck.
