Kha Y Tran In TFT Set 17 Patch 17.3, the Mecha trait is strong once again. However, the way you play it has changed. Instead of forcing 6 Mecha units, you only need 4 Mecha to build a board that can consistently reach the top four. More importantly, with the right upgrades, this comp can easily secure first place.
The main reason is the recent buff to Aurelion Sol. As a result, he now deals much more magic damage. At the same time, the Mecha Robot remains a reliable frontline. In addition, Tahm Kench gives the team even more durability. Therefore, this composition has become one of the strongest fast 8 and fast 9 strategies in the current meta.

Why the 4 Mecha Comp Is So Strong in TFT Patch 17.3
Earlier in Set 17, Mecha was one of the easiest comps to top with because of its strong damage-over-time and the Robot’s absurd durability. However, Riot nerfed both the Mecha transformation and the Robot’s defenses in Patch 17.1b, which caused the comp to fall out of the meta.
Now, in Patch 17.3, things have changed again.
Most importantly, Aurelion Sol’s buffs have significantly increased the comp’s damage output. In addition, players have realized that 4 Mecha provides all the frontline utility they need. Therefore, instead of wasting slots to chase 6 Mecha, they can fill the rest of the board with premium 4-cost and 5-cost champions.
Because of this optimization, the comp is not only more flexible, but also much stronger in the late game.
Core Champions in the 4 Mecha Comp
At level 8, your ideal board includes:
- Aurelion Sol
- Tahm Kench
- Karma
- Mecha Robot
- Three additional Mecha units
At this point, your board should be stable enough to save gold.
Level 9 Final Board
Once you reach level 9, add:
- Blitzcrank
- Rhaast
These units provide powerful utility and significantly improve your late-game strength.
