Zain first began competing in Melee tournaments in May 2014, with his first tournament being at “Smash @ Claredon”, a popular weekly event in Arlington, Virginia. He largely competed in local tournaments while in his first year at Virginia Tech, and had soon established himself as a formidable opponent among the Maryland/Virginia scene. Zain’s breakout performance at a major tournament came in 2015, when he placed 33rd at Super Smash Con 2015, which was followed by a 1st-place finish at the MD/VA Fall Arcadian, the highest non-ranked tournament in the region.

Zain’s 2017 season began with an appearance on the SSBMRank, a biannual power ranking presented by Red Bull, where he was ranked as the 66th best Melee player for his performance in 2016. A heavy influence on the ranking was his performance at The Big House 6, where he placed 17th overall including a 2–0 victory over Justin “Plup” McGrath, who was ranked 6th in the world at the time. Zain’s placing earned him some interest from Plup’s team, Panda Global, who offered him a sponsorship; however, the deal never went through. 2017 saw high placements at several major tournaments which included 5th place at Super Smash Con 2017, bumping Zain up to 22nd on the SSBMRank 2017. He was again approached by Panda Global who offered him a full sponsorship – this time, Zain accepted, with the team officially announcing the signing on April 12, 2018.

Under Panda Global, Zain enjoyed success at major tournaments including first-place finishes at *Pound* Underground, OMEGA II, and Shine 2018. However, despite his success, Zain parted ways with the team on November 8, 2019 along with teammates Cosmos and Kelazhur – no explanation for Zain’s departure was given by either the organisation or Zain himself. Following his departure from Panda Global, Zain only competed in one tournament as a free agent. Two days prior to GENESIS 7, Twitch streamer Ludwig Ahgren announced his sponsorship of Zain for the tournament under his “Mogul Moves” clothing brand on January 22, 2020. Zain won Melee singles without losing a set, defeating Hungrybox – the number-one player in the world – in grand finals. As Zain’s Mogul Moves sponsorship only lasted for the tournament, he became a free agent following GENESIS, but was soon signed by the Golden Guardians, the official esports organisation of the Golden State Warriors, on February 6, 2020. Since the signing, Zain has only competed in a few major tournaments – this was due to the COVID-19 pandemic, which prevented many live Melee events from taking place. However, with the release of the Project Slippi mod for Melee, matches and tournament could take place online. During the pandemic, Zain has won Pound Online and the Ludwig Ahgren Championship Series 2, both of which took place online.
