Nordics are a Synchro-based deck focused around summoning the Level 10 Norse Gods Loading..., Loading..., and Loading.... Each one has their own archetype built for them with Nordic Beasts for Thor, Nordic Alfars for Loki, and Nordic Ascendants for Odin. The game plan is to use these Nordic monsters in order to summon 1 of the big synchros, and have it stick throughout the entire game with their effects to constantly bring themselves back.
Allows you to gain more advantage off your Aesir monsters being destroyed and can allow you to gain some momentum after they are gone.
You should almost never have more than 1 Aesir monster on the field, so it is just a 300 ATK point boost.
Odin, Father of the Aesir:
Strongest stat wise of the Aesir monsters with pretty strong effects. Making himself unaffected by Spells and Traps for the turn can be weird since the opponent can chain to the effect with something like Loading... or a Loading..., however it does stop battle Traps. No deck currently on the Tier List can hit over an Odin so they have to rely on their effects to try to get rid of him. His on-destruction draw effect comes in very handy since you are most likely summoning him off your Loading... which costed you 3 cards from hand. This allows you to refuel especially in combination with a Skill like Baggy Sleeves.
Thor, Lord of the Aesir
The weakest effect wise of the Aesir monsters, but can be easily summonable through the Loading... combo. Negating the effects of monsters on the board can be good against things like Loading... and Crystrons, stopping their mid-turn disruption. If Thor gets resurrects then he does 800 damage to the opponent which is a 5th of their Life Points. Not a lot but sometimes it can make or break a win or loss.
Loki, Lord of the Aesir:
The weakest stat wise of the Aesir monsters but has a Loading...-like effect during your battle phase. It can make your opponent have to use their Spells and Traps at awkward times. His resurrection effect of adding a Trap Card from grave to your hand is also very powerful allowing you set up your Loading... and use it multiple times in a game. The main issue is that you need to run the Nordic Alfar Tuners for the resurrection and they make it hard to summon Loki in the first place. Definitely the hardest one to summon with its deck being a little awkward to always get going.
Vanadis of the Nordic Ascendant:
Very strong tuner. She can be used for all of the Aesir monsters with a built in level changer that thins your deck. Very strong and splashable in every different Nordic Build.
Mimir of the Nordic Ascendant:
Guldfaxe of the Nordic Beasts:
Your Nordic Beast tuner. You mainly use him as your generic tuner to go into things other than Loading... like Loading... or Loading..., using him in tandem with Loading.... His effect has future potential, but currently none of the Tier 1 or 2 decks go into synchros (however, almost all the Tier 3 decks do).
Tanngnjostr of the Nordic Beasts:
Also known as "Black Goat". His first effect can give you extra protection and help allow you to live through more turns. His second effect in combination with Loading... can create you a 1 card Loading..., Loading..., or Loading.... This is one small combo to easily create one of your synchros with ease. A lot of the decks in the meta right now are only capable of attacking once on their first turn
Tanngrisnir of the Nordic Beasts:
Also known as "White Goat". You mainly use this card as the Level 3 Nordic monster that can be summoned off of Loading.... He is also a great defensive tool to make your opponent have to attack 3 times to get through this one card.
