Noxus TFT season 9 gets increased health, AD and AP according to each champion milestone. This buff is not the first time it has appeared in DTCL season 9 , but it is increased by 10% for each different opponent that Noxus conquers or loses.
Like Ionia DTCL season 9, Noxus has a full range of damage and tank champions at every stage, the biggest difference is probably that Noxus doesn't have a 4-gold carry, you can complete the team better with just Darius or Katarina or both to have a strong carry in the mid-game. Anyway, you will need some suggestions below to complete Noxus more strongly.

Kled – Noxus, Yordle, Butcher - 2 gold

Swain – Noxus, Strategist, Mage - 2 gold

Sion – Noxus, Fighter - 5 gold
Skill:
- Passive: Upon death, revive with 100% health, decaying at 7/5/0% max health per second. Sion can no longer cast abilities, but is immune to crowd control effects and gains attack speed.
- Active: Attacks most enemies within a few adjacent tiles. Deals damage to any enemies along the way and stuns them for 1.5/2/15 seconds.

Noxus has a balanced mix of tanks and attackers from early to mid game. Samira, Cassiopeia and Katarina deal damage, Swain and Kled are tanky early, and Darius in particular can both tank and deal damage, making him a carry alongside Katarina in the mid game.
As for Sion, you can add him in late and leave out a low-cost Noxian that you don't think is effective in the late game. Sion deals damage and stuns, and he can't be controlled if he's already died once. So Sion will be the last card you need in a Noxian team.
Build items for Noxus champions in Teamfight Tactics season 9
DTCL season 9 equipment will be for magic items for Katarina and Cassiopeia, Cass will help Katarina with items, both need items like Sparring Gloves, Tears, Oversized Rod, and Silver Cloak. The necessary complete equipment for both can be Jeweled Gloves, Hand of Justice, Tears, Spear of Shojin, Hextech Gunblade, and Thunderbow. You can also throw these items to Swain, he can get Piercing Mace to deal better damage.
Physical damage or skill support items will be for Samira, Kled and Darius, including some equipment such as Last Whisper, Titan's Grasp, Hand of the Gods, Infinity Edge, Hurricane Bow, Deathblade, Rageblade...
As for Sion, he probably only needs tank items, or skill support items like Hand of Justice, Piercing Mace. Tanky items like Fire Vest, Thornmail, Redemption, Blood Armor, Gargoyle Stoneplate.

Early game
It's simple, like many strong DTCL teams that are just starting out and building at the beginning of the game. With 4 champions, choose 2 damage dealers and 2 tanks. You can choose Swain to stand with Kled, but you can choose Warwick to have more Challenger for Samira and Warwick to deal damage faster.

Mid game
Level up to 6 Noxus or you can keep 3 Noxus and add other champions for more buffs. Or level up to 6 Noxus as shown below and start saving money to roll for Katarina and Darius if you intend to roll for one of these two champions to 3 at level 7, or you can roll for both.

End Game
6 Noxus
This is the team you should aim for if you are going to slowroll Katarina and Darius at level 7, you may not need Sion to complete the team. Additionally, you can also roll Swain and other Noxians to 3 stars if you have the chance.

Or you can change to the team below if you see Sion appear more often, he definitely wants to appear in the team to "charge" all enemy generals. If you don't save money to roll for Katarina with Darius, then level up to level 8 early to increase the rate of Sion.

On a more difficult plan, if you can get the Noxian mark (Golden Shovel + Giant's Belt), then Aatrox is the most suitable champion to give him, Aatrox's increased health, AP and AD will help him deal better damage, Aatrox can also revive from his allies. Since he can stand in any team composition, Aatrox is the most suitable choice to combine. Going for 4 Butchers will increase Aatrox's lifesteal and damage if possible.

3 Noxus
Another team you can aim for is the one below, this team is not really Noxian like the teams above but will have many different races and champions in the team. Adding Freljord will help the team have more control for Aatrox, Urgot and 3 Noxian champions to deal damage. You should only take this team if you have a lot of money, and have at least 3-star Katarina or Darius.

9 Noxus
9 Noxus only happens when the player has the buff and Noxus seal and just stops at level 8. Aatrox definitely holds the Noxus seal, and you also need a lot of money to level 8 quickly to meet Sion and activate 9 Noxus.
At this point, you will have all your buffs drained, leaving you with only 9 Noxus and Destroyer, Butcher, but your health, AP and AD will be increased. Enough so that you don't need to activate more buffs thanks to other champions.

In general, Noxus has many directions because it can be combined with many different clans. You can use slowroll to get 2 3-star mains or quickly level up to 8 to get Sion and turn him into a late-game main.
Noxus's only weakness is that it doesn't have a 4-gold carry like other races, so the late game only focuses on Sion. Hopefully in season 9.5, Draven, Riven, Talon or Vladimir will appear to carry 4-gold champions, because usually the main force in the late game will be 4 gold, sometimes 5 gold is just a secondary carry.
