With the changes in patch 12.15, many old team compositions are making a comeback in Teamfight Tactics.
Jade Dragon
Despite Shi Oh Yu being weakened in patch 12.15, it's not enough to make Jade Dragon disappear. Even with other main champions weakened, a team comp that's easy to build, strong from start to finish, and flexible in selecting champions like Jade Dragon becomes even stronger. Besides Shi Oh Yu, Anivia is also a powerhouse with magic damage items like Morellonomicon and Rabadon's Deathcap.
Not stopping there, the Jade Dragon composition also has another strength: having quite a few empty slots to be flexible in choosing champions late game. You can definitely bring in strong characters like Yasuo, Bard to the field to add damage and control to the team comp. The rare weakness of this team comp is that you'll have to compete fiercely with other players as the selection rate for Jade Dragon is currently very high.
Ranger - Blademaster
In the previous patch, the Sharpshooters - Duelists composition almost disappeared completely when Varus received a significant nerf at 3-star level. However, in patch 12.15, this composition is making a strong comeback even though the main carry (Varus) hasn't been buffed. The main reason for this is Ezreal and Twitch being buffed and helping the Sharpshooters - Duelists comp sustain much better in the early game.
The above reason will help the Sharpshooters - Duelists composition gain a lot more gold due to winning streaks in the mid-game, making the process of rolling for a 3-star Varus much easier. Furthermore, the increase in Xayah's strength will make the damage output of the Sharpshooters - Duelists lineup much stronger in the late game and not solely dependent on Varus anymore. So if you want to use a familiar composition to climb in the new patch, Sharpshooters - Duelists is a highly suitable choice.
Galio and His Allies
Fundamentally, Corki's situation is quite similar to Shi Oh Yu, where Riot's nerfs are too small to make this champion disappear completely. Even with flexibility in building the team composition, Corki and His Allies become very unpredictable. You can choose Idas, SyFen, or even Shyvana as frontline tanks while Corki still deals significant damage in the backline.
While Corki's interaction with SMCK has been reduced, this unit is still a Festival champion with the ability to deal additional magic damage. So that nerf almost has no effect, and Corki remains very strong in patch 12.15. With Riot Games' tendency not to make significant adjustments before mid-season updates, Corki might continue to dominate Teamfight Tactics for a long time.
