Gunner – Festival
Known as one of the easiest compositions to get accustomed to in Teamfight Tactics Season 7, the Gunner – Festival team has gradually fallen into obscurity after a short period of time. The main reason for this situation is that Corki faced a significant bug where large fireworks would fly off the battlefield if the target was defeated on its way. This resulted in Corki suffering a lot of damage and being less effective than other carries.

The fate of the Gunner team promises to become much brighter in the upcoming patch 12.12 when Riot fixes the aforementioned bug of Corki and allows the large fireworks to explode and deal damage on the battlefield. Furthermore, the Gunner system itself has also received a significant buff in its area damage capability, allowing carries like Corki and Tristana to deal damage much more effectively. With these direct buff actions, the likelihood of the Gunner – Festival team rising in patch 12.12 is very high.
Mythic
This is a very interesting composition in Season 7 where you will sacrifice units on the board to empower Mythic champions with immense power. However, the critical weakness of this composition is its vulnerability to Assassins, as the backline lacks adequate protection. Coupled with the emergence of several compositions using Olaf from the Dragon tribe in the current meta, the Mythic composition has almost no chance of making it into the list of the strongest teams.

However, in the upcoming patch 12.12, the Mythic tribe will receive a strong buff as the ability to absorb damage from this tribe’s skills is increased. Moreover, the key carry of the Mythic, Volibear, has been significantly buffed in terms of area damage as well as the champion’s basic attack speed. Therefore, equipping Volibear to have a strong carry at the front line will be an extremely reasonable choice.
Swain – Dragon Warrior
Perhaps with Sett capturing all the attention of players, people have forgotten that the Dragon Warrior tribe also has a very strong 3-cost carry, Swain. Simply put, in the hyper-roll Sett composition, Swain only plays a role in activating the tribe. However, with a strong Dragon Warrior composition in the mid-game, the buff aimed at Swain is extremely noteworthy. This could help Swain make a comeback in the game meta.

A tip when playing this team comp is to early combine Statikk Shiv for Swain or another unit to take advantage of the damage output this unit provides. In the late game, the ability to reduce magic resistance on multiple targets is extremely synergistic with Swain. Additionally, you should use multiple shapeshift units to help this unit gain more health and survive in fights much longer.
