Void
Currently, the power of the Void trait in Teamfight Tactics is facing several issues. Essentially, the summoned units are only valuable for their tanking capabilities if players do not reach the 8-unit threshold with Baron. Additionally, the damage output of the Void composition heavily relies on Kai’Sa towards the end of the game.

Therefore, in the upcoming patch 13.14, Riot will comprehensively buff the Void composition. First, the health and damage output of the Rift Herald will be increased. Following that, a series of champions like Cho’Gath and Malzahar will receive buffs to their damage output. These changes promise to significantly bolster the Void trait.
Mystic
Although not a weak composition, Mystic is currently facing many challenges. With the use of numerous backline champions, Mystic is heavily countered by compositions centered around Zed or Katarina. Given the popularity of these units, Mystic has little opportunity to shine.

In patch 13.14, Riot will significantly enhance Galio’s tanking capabilities as a solution to this problem. The damage of Soraka and Karma will also be buffed in this patch to help the Mystic composition eliminate opponents faster. Additionally, both Zed and Katarina will be nerfed in patch 13.14, creating a great opportunity for Mystic.
Akshan – Marksman
Essentially, the Akshan – Marksman composition faces similar issues to Mystic, being heavily countered by Zed and Katarina. Therefore, in patch 13.14, this composition is sure to become stronger with the nerfs to Zed and Katarina.

Furthermore, both Akshan and Ashe (the main Marksman champions in the composition) will have their damage output increased. Additionally, other key units like Sejuani, Lissandra, and Jarvan IV will not be altered. Therefore, the Akshan – Marksman composition promises to be a very strong playstyle in the upcoming patch.
Conclusion
With significant buffs, compositions like Void, Mystic, and Akshan – Marksman are expected to rise powerfully in the upcoming patch 13.14. Players should take advantage of these compositions to rank up more effectively in the future.
