New Strength of the Challenger System
In Teamfight Tactics season 9.5, the Challenger system has added 2 new units, Fiora and Naafiri. These are both powerful champions with skills that deal effective damage and significantly strengthen the Challenger composition. The greatest strength of Fiora is that this unit possesses the ability to deal true damage and counter other melee carries.

Meanwhile, Naafiri with the Darkin trait provides incredibly useful lifesteal stats for the carry. This helps the carry in the Challenger composition deal damage and hold their ground in fights extremely well. As a result, players can easily secure victories and rank up effectively.
Building the Challenger – Strategist Composition
At the beginning of the game, players should aim to acquire Samira early to ensure damage output. Next, activating the Noxus trait with Swain and Cassiopeia is essential to increase durability. Naafiri is also a unit that should be purchased at this stage when activating the 2 Shurima threshold with Cassiopeia.

By the mid-game, players should add Warwick and Irelia to reach the 4 Challenger threshold. This will significantly enhance the carry’s damage output and may lead to a winning streak for the player. Additionally, players should equip Warwick with the Moonstone Cloak to enhance armor reduction capabilities.

After reaching level 8, players should use their gold to search for Fiora and Kai’Sa as carries. Jarvan IV and Quinn are also champions to be added to activate the 3 Demacia threshold. If lucky, Aatrox will be a perfect addition to this composition when activating multiple traits and the powerful Darkin effect.

Regarding Legendary choices, Ezreal and Twisted Fate are quite suitable for a composition that uses multiple carries like Challenger. For item choices, Bloodthirster and Titan’s Might are the best fits for Fiora. Kai’Sa will need spell power and energy regeneration items like Spear of Shojin, Guardian Angel, and Archangel’s Staff.
Conclusion
With Fiora’s rise in recent times, the Challenger composition is proving to be extremely strong at this moment. If Teamfight Tactics players are looking for an effective ranking strategy, Challenger – Strategist is an excellent choice.
