The following team compositions have received numerous buffs, both direct and indirect, and have become incredibly strong in Teamfight Tactics patch 12.6.
Technology
Among the races and classes adjusted in patch 12.6, Technology emerges as the biggest beneficiary. Its early game strength often fades as the match progresses. Therefore, in patch 12.6, Riot has bolstered the power potential of this class by increasing the value of shields and damage based on the number of technology cores owned by players.

This ensures that the strength of the Technology class remains stable, avoiding the scenario of being strong early but weak late game. Additionally, with Riot nerfing the SMCK of many champions, the spell damage effect provided by the Technology class becomes even more vital. Perhaps in the upcoming patch, players utilizing Technology teams will gradually transition to using attack speed items for their carries to maximize this effect.
Warwick reroll
As we know, in the upcoming 12.6 patch, Riot will nerf the base SMCK of 31 champions priced from 1 to 5 gold to reduce the impact of physical damage team compositions. Among the champions affected, Warwick is perhaps the least affected as he does not rely heavily on SMCK stats. With innate spell damage and healing on attacks, even if the base SMCK is further nerfed, this unit still deals effective damage.

Furthermore, with a series of 4-gold champion-based team compositions being nerfed, the high probability reroll strategy will likely dominate the Teamfight Tactics meta once again. Clearly, after the nerf in patch 12.5b, Warwick, as a rare champion, still retains enough power when upgraded to 3-star at 2 gold cost. Moreover, the Warwick-centric Hextech - Duel composition becomes much stronger when the Vanguard trait requires 3 champions to activate its effect.
Jhin and his companions
Among the champions with reduced SMCK in patch 12.6, Jhin is among the least affected, with only a 5-point reduction. So, it can be said that Jhin is not nerfed too severely, especially when this champion reaches 2-star level. Additionally, adjustments targeting the Inventor trait do not affect team compositions revolving around Jhin, as they still utilize all 5 champions of this trait.

The main reason why Jhin-centric team compositions shine in the subsequent patch is that units with the ability to quickly access the backline are no longer too dangerous, with Irelia being a prime example. Therefore, Jhin will have plenty of time to deal damage without fear of being interrupted by the Sân Khấu Tử Thần ability halfway through being subdued. Clearly, as the meta shifts towards selecting team compositions that attack from the back to the front, Jhin will undoubtedly have a very strong position.
