At the end of the group stage of the Chinese Taipei Mobile League Garena Challenger Series (GCS) in the summer of 2021, One Team led with a convincing achievement. Ranked after the spring champion, Hong Kong Attitude and Mad Team.

Entering the play-off round, HKA defeated Mop 4-2 to face One, the team buried Mad 4-1 in the finals of Thang branch. Here, HKA lost to One quickly with a score of 1-4, thereby falling to the final of the losing branch, where they encountered Mad. Earlier, Mad had an impressive comeback to turn MOP early into a former king with a final score of 4-3.
In the final of the lost branch, HKA was led 0-2 and 1-3 but finally “passed the waterfall” successfully to win 4-3 choking. Thang entered the final with One, HKA performed a different face that was different from what happened in the final of Thang branch.
With a super -structured squad and the ability to control the great soldier, HKA completely overwhelmed to win in game 1 after less than 13 minutes. One equalized in game 2 thanks to the early Kai Gunner with the Violet card but at game 3, the shocking squad helped HKA overcome.
HKA has won in game 4 hinges thanks to the squad, including all the standard meta generals, including 2 gunners. However, One also proves why they reached two consecutive GCS finals when they calmly removed 2 games, bringing the final match to game 7 decisions.

Once again, HKA uses 2 gunner. Dada was green early with Eland'rr, plus Tachi was too strong to help HKA create a “snow -rolling” match. One tried to support but before HKA's terrible damage and firm barrier, they had to be helpless to become the second runner -up for the second time in a row.
For HKA, this is a worthy achievement for their efforts despite the major changes in the squad. Theman left, Xiaolin had to switch to the gunner, but fortunately the rookie Dada and in particular, Xixi shines to compensate for the shortcomings to help HKA become the new King GCS, and win tickets to AIC as the No. 1 seed of Taipei China.
