Riot’s mutation adjustments in TFT 12.19 brought a lot of confusion about the order of strength of the squads.
Dragon Guild Squad

After a series of adjustments, Tung Tung – General Dragon of the Guild was no longer as wasteful as the new season 7.5 launch period. Now this general can choose a “smarter” target and be able to be the main force in the squad.
Besides, Jayce’s rework is also a bright spot for the Guild in 12.19. Despite losing the ability to knock up when transforming, Jayce now has more resistance than before, thereby creating a balance for this squad. Combined with Earth Dragon Terra, this will be the version that helps Tung Tung and Jayce maximize their strength at the end of the game.
Lineup at level 8: Sejuani, Twitch, Tung Tung, Jayce, Bard, Terra.
Team Ngoc Long – Dark Dragon

Emerging from the previous patch with a stable top 4, the Jade Dragon lineup will now be even stronger in 12.19 when Gnar and Shi Oh Yu get a significant boost in Damage. That makes it easier to build this squad in the early game while still ensuring the amount of Damage later.
Normally, this squad will follow the style of full Ngoc Long, but at the moment, clamping more Sy’Fen and Pantheon to activate 4 Dark Dragons will bring greater efficiency. Besides, Jayce is also an indispensable factor to complete this unique lineup.
Lineup at level 8: Jax, Gnar, Shi Oh Yu, Pantheon, Sy’Fen, Jayce.
Mam Ma Mage Squad

Since the increase in the quality of the Upper Dragon, the roster around Sylas and the Mages is actually quite easy to deploy from the early game. However, the most perfect combination is Mam Ma when this general has a Mage Tribe.
With a barrier consisting of many 3-star generals from the reroll process, Mam Mam and Lux will be prestigious cannons to deal a large amount of Damage to the opponent’s squad. Of course, in the case that Mam Ma has a different Tribe, the player can still switch to a full Thuong Long size and take advantage of the power from Aurelion Sol towards the end of the game.
Squad at level 8: Skarner, Vladimir, Lillia, Lux, Sylas, Mam, Zoe.

Dragon Warrior slowroll lineup

After removing Nunu’s hegemonic power, Riot was assured of increasing the activation stats of Dragon Warrior, thereby creating conditions for the rest of the generals in this Tribe to shine. Immediately, the community discovered this was the right time to build a slowroll squad.
With the main force being Karma and Lee Sin, this Dragon Warrior lineup will take advantage of their superior strength at the beginning of the game, thereby trying to roll the aforementioned generals to 3 stars as soon as possible. In addition to pushing the opponent’s health well in the early stages, this squad is still strong enough to last until the end of the game when adding quality cards like Bard, Yasuo.
Squad at level 7: Karma, Sett, Kai’Sa, Lee Sin, Volibear, Yasuo, Bard (Dragon Warrior Seal).
Exodia Dragon God Squad

With the destructive power at the end of the game, it is clear that the 4 Dragon lineup is really a reward for players who can persevere through the early game to aim. With comprehensive defense and the ability to freely choose different Dragon generals, this squad really has a great charm in season 7.5.
Basically, the mainstays are still Aurelion Sol and Shyvana, and Idas and Terra are two tank champions to bring a balance factor. Rakan is the remaining champion chosen the most to be able to activate the Tribe as well as increase the ability to apply effects.
Lineup at level 9: Aurelion Sol, Shyvana, Terra, Idas, Rakan.
