The meta is favoring Aurelion Sol
After the heavy nerf to the Hacker trait, the playstyle revolving around long-range carries is making a comeback in Teamfight Tactics. Therefore, players must seek alternative solutions to attack the enemy’s backline without relying on Hackers. In this context, Aurelion Sol has emerged as an extremely powerful countermeasure.

Simply put, the meteors summoned by Aurelion Sol will randomly fall on the enemy’s formation. Therefore, no matter how well-protected the backline champions are, they will still take damage from this unit. Combined with strong Hero Augments, Aurelion Sol can help players secure easy victories.
Building Aurelion Sol – Protector Composition
Since a lot of gold is needed to reach level 8 and upgrade Aurelion Sol, the Scavenger trait will be a reasonable starting point for this playstyle. With the Scavenger trait, players will possess a massive amount of resources mid-game to pivot to Aurelion Sol and the Protector champions. Champions like Ezreal and Lucian will hold items very well in the early game.

In the mid-game stage, players need to add Protector champions to the composition to ensure durability. If you have Aurelion Sol at 1 star, then taking the Scavenger reward will provide enough gold and items to pivot later. Additionally, Morgana is a champion that should be purchased at this stage as she provides decent crowd control and damage.

After reaching level 8, players need to use resources to upgrade key champions. Aurelion Sol, Aatrox, and Ekko will be top targets at this stage as they provide good damage and durability for the composition. Additionally, Fiddlesticks and Leona are also solid choices at this time.

Regarding the Augments, Elemental Essence is a very strong upgrade for the Aurelion Sol-oriented composition. Additionally, the Ultimate Event Core also provides this unit with excellent clearing ability. For item choices, the Spear of Shojin is the most important item for Aurelion Sol. The other two slots should be filled with items that increase magic damage to help this unit quickly take down opponents.
Conclusion
With the Teamfight Tactics meta changing, Aurelion Sol has emerged as a strong choice to counter long-range carries. This is expected to be the “ace in the hole” for players when competing against other popular compositions that are highly contested.
