From left to right, "Loki", "Odin" and "Thor" (with Odin holding "Nordic Relic Gungnir" and wearing "Nordic Relic Draupnir") towering over Team Ragnarok.
"Aesir", known as "Polar God" or "Three Polar Gods of the Star World" (
In the Japanese anime, the "Aesir" are currently the only DIVINE Divine-Beast-Type Synchro Monsters ever seen, as well as the first DIVINE monsters of any kind since the Egyptian Gods. However, their Attributes and Types were changed in the OCG. "Loki, Lord of the Aesir" is a DARK Spellcaster, "Thor, Lord of the Aesir" is an EARTH Beast-Warrior and "Odin, Father of the Aesir" is a LIGHT Fairy. Each member of Team Ragnarok possesses one of these cards.

The three cards are named after the top three Gods in the Norse mythology pantheon. The God King is Odin, The God of Thunder is Thor, and the Giant treated as the God of trickery is Loki. In Norse mythology, these 3 gods are said to form part of a huge battle known as Ragnarök in which they will die. They can be considered Polar Gods due to the prelude of Ragnarök known as Fimbulvetr, which is a time of three winters with snow coming from all directions without any summers between. During this time, there will be wars, brothers killing brothers and eventually all life on Earth will be destroyed. They can also be considered Polar Gods due to their association with Scandinavia and Nordic Countries (located within Scandinavia) which itself is located north extending to the Arctic Circle.
In the anime, these cards were found in caves with tree roots surrounding their interior by the Duelists they engraved the Rune Eyes upon. The roots in these caves are probably an allusion to the world tree of Norse Mythology, Yggdrasil.
The name "Aesir" is essentially meant to be the term Æsir, the term used to identify an entity from Norse paganism, which includes all three of the Polar Gods' original gods. This is because the grapheme "Æ", a ligature, is formed from "A" and "E" - and in places where the grapheme is either difficult to use or otherwise unsuited, the two-letter set "Ae" is often used as a replacement. (It is notable that this replacement would be improper for languages where "Æ" is a letter; one such language is the language where the term "Æsir" comes from, Danish).
The powers of these gods rival that of the Crimson Dragon. When "Thor" clashed with "Red Dragon Archfiend", both monsters emitted a strange energy pulse, wreaking havoc around the dueling arena and drastically upsetting the weather outside the stadium. During Team Ragnarok's match against Team 5D's, the attacks of the Aesir dealt real damage to Jack and Crow.
A Double Aesir Deck is a Deck that revolves around two Nordic sub-archetypes, Nordic Ascendant and Nordic Beasts. It is one of the most commonly used deck that revolves around the Nordic. The main goal is to summon Odin, Father of the Aesir and Thor, Lord of the Aesir to lock your opponent from using Spell Card, Trap Card or Effect Monster's effect and have atleast 1 beatstick on the field. It is not actually recommended to use Loki, Lord of the Aesir.
One way to summon "Odin, Father of the Aesir" is to use the effect of "Valkyrie of the Nordic Ascendant" to summon two "Einherjar Tokens", then Synchro Summon Odin. This can be done on the player's first turn if the right conditions are met. If your first turn is before your opponent's, or you choose not to use the effect of "Valkyrie of the Nordic Ascendant", you can use 2 copies of "Statue of the Wicked" as substitutes for the Synchro Material Monster requirements.
However, many decks exclude "Valkyrie" due to the difficult conditions in using its effect, and the high potential hand loss if it is negated. Because of this, "Vanadis of the Nordic Ascendant" is usually used, for versatile Synchro Summoning, deck thinning, and its ability to help Synchro Summon both "Thor, Lord of the Aesir" and "Loki, Lord of the Aesir". However, be advised that "Vanadis" can only be tuned with other "Nordic" monsters.
There are many ways to summon Thor, Lord of the Aesir due to the powerful swarming effects of the Nordic Beasts and the Beast support cards. One way is to have your opponent attack your Tanngrisnir of the Nordic Beasts then you can summon two tokens and special Tanngnjostr of the Nordic Beasts with its effect in defense position. Next turn you can change the battle position of Tanngnjostr of the Nordic Beasts and search for the key Tuner monster, Guldfaxe of the Nordic Beasts. Normal summon Guldfaxe of the Nordic Beasts and then tune it with two tokens to summon Thor, Lord of the Aesir.
