Nordic

Odin's spear, which never misses and always kills.

Odin's gold ring that multiplies itself; here his hand produces another relic, as the card fetches one.

Odin's Valkyries gathered fallen warriors, the Einherjar, for Valhalla, and her effect makes Einherjar Tokens.

The thunder god. The handle of his hammer is the thurisaz rune, Thor's own, and he is the only Aesir whose effect hits monsters.

One of the goats that pull Thor's chariot; the name means "teeth grinder", and in 5D's episode 124 it grinds its teeth while summoning Thor.

Gullfaxi, the golden-maned horse, second in speed only to Odin's Sleipnir.

The trickster, drawn from the Reginsmál: big nose, goatee, small pointed hat. Tricks of his own: he negates Traps.

The dvergar, the dwarves of the mountains: a Warrior, unlike the other Alfar, and it recovers Nordic Relics, which dwarves forged.

The mara rides sleepers' chests and gives them bad dreams: the root of "nightmare".

Loki's wolf son, fated to kill Odin at Ragnarök. It is bound by Gleipnir until it breaks free.

The chain that holds Fenrir until Ragnarök, the last of the three fetters the gods made for him, after Leyding and Dromi.

The serpent that rings the world with its tail in its mouth; when it lets go, Ragnarök begins. In 5D's it holds its tail in Defense Position and lets go in Attack. At Ragnarök it and Thor kill each other.

The war god whose right hand Fenrir bit off: his right arm is covered.

The Northern Lights, by a pun.
