Mountain debuted with the Flash Wolves during GPL Spring 2014. He was the former Gamania Bears roster's direct replacement for Winds, who had transferred over to Taipei Snipers after 2013. The team qualified for the playoffs, but were quickly dispatched by their former teammate as the Snipers knocked them out 3-0.
The Flash Wolves failed to retain their seat in the GPL the summer after, and played through the LoL Nova League instead. They placed second behind the Taipei Snipers.
Mountain temporarily replaced Winds again on the Taipei Snipers during the 2014 Season Garena Regional Finals, losing 2-3 to Saigon Fantastic Five.
Placed directly into the finals of the gauntlet-style playoffs, they once again won the season, this time beating Hong Kong Esports 3-0 and automatically qualifying for the 2015 Season World Championship.
At Worlds, ahq were seeded into Group B, along with Fnatic, Invictus Gaming, and Cloud9 and went 3-3, advancing to the playoffs after a tiebreaker victory over Cloud9 (giving the North American team their fourth loss in a row that day). Their World Championship run ended in the quarterfinals, where they were drawn against tournament favorites SK Telecom, earning a top 8 finish.
