Due to their excessive “overpowered” strength in the previous update, many hot champions like Jinx, Aurelion Sol, Vayne, Urgot, Ezreal,… have been significantly nerfed. Conversely, many other champions have been buffed to an incredible extent, resulting in many compositions becoming stronger in the meta.
Here are the strongest team compositions in TFT patch 10.14:
6 Super Tech Composition

In previous patches, Irelia was not weak at all; in fact, reaching Irelia 3 stars was almost “unbeatable”. However, for some reason, in patch 10.14, this Blade Mistress has been overly buffed by Riot, with increased health, damage, armor, doubled magic resistance, and increased skill damage. Irelia’s buffs completely overshadowed Vayne, Vi, and the activation of 3/6 Super Tech, which were slightly nerfed in patch 10.14.

With Vayne no longer being the main carry, activating Marksman will be unnecessary. Thus, Shen will be the right champion to activate Blade Master and Time Warp for Irelia, while also countering powerful champions like Jhin or Xayah in 10.14.
For items on Irelia, Guardian Angel will be quite important since Urgot in 10.14 cannot ignore Guardian Angel to take down targets anymore; Urgot’s skill will hit the first target it encounters, and since Irelia “jumps around” continuously, it’s quite necessary to be revived after getting hit by stray shots.
Shadow Marksman Composition

After many updates of being “absent”, Shadow has finally made a comeback thanks to Riot Games buffing 5 Shadow champions: Jarvan, Jhin, Karma, Mordekaiser, and Shaco. Among them, Jhin is the most noteworthy due to increased damage both in auto-attacks and skills, along with increased attack speed.

With this massive buff, the Shadow composition has “shot up” to become one of the top compositions in the meta. Even Xerath, a champion that wasn’t popular in the previous patch, has now become a perfect piece to compensate for the lack of magic damage in the Shadow composition. Jhin will be the main carry with enormous damage in this patch 10.14.
Xayah Shredder Composition

In patch 10.14, a multitude of champions in this composition have been buffed, such as Jarvan IV, Xayah, Rakan, and Ashe, making this composition not just hot, but even hotter.
The reason this late-game weak composition is favored in the Diamond rank across many servers is due to its superior strength in the early to mid-game phases. This allows players to easily reach the top 4 in fast-paced matches within the Diamond rank. Now, the early-game composition is even stronger as “cheap champions” have been buffed further, making the fast-paced playstyle even more effective. Additionally, the activation of Universe has been slightly increased in healing from 15/40/99% to 20/45/150%.

The typical playstyle for this composition remains the same; you will need to hyper-roll for champions like Xayah, Jarvan IV, Rakan, Fiora, or Shen at level 5 or 6 depending on the match. If you have Riven, she can replace Fiora (activating both Blade Master and Time Warp).
Celestial Guardian Sorcerer Composition

With a massive buff in patch 10.14, Syndra has become the main carry in the Sorcerer composition combined with Celestial Guardians (CG). So strong that Riot immediately released a patch to adjust Syndra’s energy from 40 to 50, but even so, Syndra remains too strong thanks to increased skill damage at 2 and 3 stars.
Additionally, other CG champions have had their total energy cost for their skills reduced, while the CG passive will be significantly weakened at the 6/9 activation. Luckily, this composition only uses the 3 CG passive, so it won’t be significantly weakened.

Regarding the new playstyle, since Neeko has been slightly buffed, she can still be utilized in this composition, while Syndra will continuously spam her skills to eliminate enemies with her massive damage. If equipped with Guardian Angel, Syndra will continuously create shields for herself, maximizing her survivability.
