The Senna lineup is proving highly efficient and can be applied in high-ranking tiers as well.
TFT Season 10 marks Riot's decision to end mid-season breaks, resulting in a single continuous season. Gamers have been eagerly awaiting this change, hoping for an exciting TFT season to enhance the game mode's appeal. So far, this expectation has been met well, with no excessively dominant chess pieces.

Nevertheless, there are still some cost-effective lineups for gamers to climb ranks effectively, especially in lower tiers. Specifically, the Senna-centric lineup is currently showing considerable strength. It's an easy-to-assemble lineup, allowing players to have strong carries from early levels and maintain consistent gameplay throughout.
Overview and Operation
The primary strength of the Senna lineup lies in Senna carrying two highly popular Tribes and Traits: True Damage and Slayer. The advantage of these two Tribes and Traits is their synergy with current 'hot meta' champions like Yone, Aphelios, or even higher-tier ones like Akali and Lucian. Furthermore, as long as one of the two Tribes and Traits is activated Super Star, players can easily pass through the early stages (2 True Damage or 2 Slayer).

However, like any lineup centered around budget champions, the demand for precise itemization is paramount. Therefore, players need to equip Senna with suitable items and adapt according to the match situation. Additionally, upgrading Senna to 3 stars early is crucial to gain an advantage towards the end of the match.
Team Composition
At the early levels, players can easily acquire a Super Star Senna as this champion costs only 2 gold. Furthermore, they can incorporate K'Sante - Yasuo/Jinx and any Guardian tribe champions at level 4 to form a sufficiently robust early-game team.

In building a team around Senna, gold should be prioritized for rolling champions rather than leveling up. Getting Senna to 3 stars sooner will provide players with more time to build the necessary team composition and make reasonable choices to play around Senna. At levels 5 and 6, the initial Guardians can be replaced with Ekko. If Aphelios is available, he should be included to trigger 4 Slayer (if the Slayer Super Star effect is active). In the case of True Damage, a Guardian can be added to trigger 4 Guardians, increasing the team's shield.

In the late game, it's essential to finalize the team composition with a core of 4 True Damage - 4 Slayer - 4 Guardians. A notable advantage is that Senna shares a Tribe with many champions with 3 or more Tribes, making it easy to assemble the team. A perfect team composition at level 8 consists of:
For Super Star Slayer Senna: K'Sante - Mordekaiser - Ekko - Blitzcrank - Senna - Lucian - Aphelios - Yone. At level 9, Akali can be added to trigger 4 True Damage.
For Super Star True Damage Senna: K'Sante - Mordekaiser - Blitzcrank - Ekko - Senna - Lucian - Akali - Karthus.


Technology Core
With this lineup, the Technology Cores provide strength for both the True Damage and Slayer tribes, making them effective. Additionally, Cores providing bonuses to True Damage or Slayer traits also make it easier for players to build the team. However, players need to monitor the situation and have contingency plans in case many players want to 'spam' certain champions.
