After version 12.5b appeared, it is not difficult to realize that the Inventor squad is dominating the Teamfight Tactics meta.
Basically, the Jhin – Canh Binh formation will work like regular Gunner formations, taking advantage of the long range of the main force to win.
For Assassin formations, the 4 Guards effect can also cause its attack circuit to be stopped when Talon or Twitch will be locked for a long time.
To build this squad, you should start with the Gladiator – Gunner team and take advantage of cheap, quality units like Caitlyn, Sejuani, Illaoi.
At the end of the game, you need to `spend money` at level 8 to upgrade important 4-cost pieces like Jhin, Vi or Orianna to 2 stars.
The most important technology core for the Jhin – Canh Binh team is the Sniper Nest as it directly increases the Gunners’ output damage by up to 40% even if it is only a Silver level core.
With `powerful` equipment, the trio of Infinity Sword, Blue Bow, and Giant Slayer is still the optimal choice for Jhin.
