Challenger
With the adjustments in Teamfight Tactics Season 9.5, Challenger continues to be an extremely powerful playstyle. The addition of two strong units, Naafiri and Fiora, ensures that this composition can output significant damage from mid to late game. Furthermore, Fiora’s ability to deal true damage is incredibly useful at this time.

Another factor that makes Challenger an effective rank climbing option is its easy build. Players can reach the 4 Challenger threshold with substantial mid-game damage using only 1-2 cost champions. This will create a good foundation for accumulating gold to upgrade Kai’Sa or Fiora in the later stages.
Noxus
Essentially, the playstyle of Noxus in Teamfight Tactics Season 9.5 still relies on leveraging additional stats to snowball. This familiarity will help players quickly adapt and climb ranks effectively in the current Season 9.5.

Moreover, the Noxus playstyle in this mid-season update has become more versatile with the presence of Mordekaiser. Instead of trying to upgrade Darius and Katarina to 3 stars, players can focus on leveling up to 8 and utilizing the Armored Demon. With the Rapid Firecannon, Mordekaiser is fully capable of “carrying the team” to victory.
Void
Despite featuring many new champions, the playstyle of the Void composition in Season 9.5 remains quite familiar to players. Players will still seek to upgrade the two main units, Qiyana (replacing Zed) and Katarina, to ensure damage output. In fact, the early game strength of the Void composition has improved as Graves proves to be significantly stronger than Viego.

Furthermore, with the inclusion of the Ixtal trait, Void champions also possess the ability to deal burst damage or tank exceptionally well. These factors are helping the Void composition maintain a quite comprehensive strength at this moment.
Conclusion
With great power and easy construction, compositions like Challenger, Noxus, and Void are proving to be quite strong. Players should take full advantage of these compositions to climb ranks more effectively at this time.
