While he only received some playing time in the 2021 Spring Split, since then, Oner has reached six LCK Finals, including a win in the 2022 Spring Split. He reached the Finals of the World Championship in his first year as a starter, and the following three years, he won the 2023, 2024 and 2025 editions of the World Championship.

Oner's individual accomplishments include accolades such as an LCK Finals MVP award, four LCK Jungler of the Year awards, and one LCK First All-Pro Team designations.

Professional career In 2020, Oner was signed to T1 Academy, the developmental team of T1. After turning 17 on January 31, 2021, he made his LCK debut on February 21 in a win over Liiv SANDBOX in the 2021 LCK Spring Split regular season.

In the 2022 LCK Spring Split regular season, Oner was a member of the T1 team that went undefeated in the regular season with a 18–0 record, becoming the first team to achieve this record in the LCK. Moon won his first LCK title in the 2022 LCK Spring finals.

Moon and T1 reached 2023 LCK Spring finals, where they lost to Gen.G. By finishing second place, T1 qualified for the 2023 Mid-Season Invitational as the second seed, where they were defeated 3–2 by JD Gaming and 3–1 by Bilibili Gaming, exiting the Mid-Season Invitational at the loser-bracket final. T1 finished second in the 2023 LCK Summer Finals in another rematch against Gen.G. With the most championship points in the LCK, the team qualified for the 2023 World Championship, marking Oner's third Worlds appearance. T1 won their fourth Worlds title on November 19, 2023, after defeating Weibo Gaming in the finals by 3–0 score.

In the Spring Split of the LCK, T1 finished with a regular season record of 15–3, placing second behind Gen.G (which went 17–1). In the Spring Playoffs, T1 reached the finals but lost to Gen.G, finishing as runner-up of the split. As a result of their placement, they qualified for the mid-season international competition. At the 2024 Mid‑Season Invitational (MSI), T1 entered from the LCK and progressed through the play-in stage and bracket stage. In the bracket stage they defeated G2 Esports and Team Liquid but ultimately lost in the Lower-Bracket Final to Bilibili Gaming (3–2) and took third place overall. During the Summer Split, T1's performance declined relative to spring: they ended the regular season 11–7, placing 4th. In the Summer Playoffs, they defeated KT Rolster in Round 1, but were then swept 0–3 by Hanwha Life Esports in Round 2. They fought through the lower bracket, defeated Dplus KIA, but were eliminated after a 1–3 loss to Hanwha Life in the Lower-Bracket Final. Their route to qualification and the final reflected a resilience despite their weaker domestic summer showing.

With T1 heading into the 2025 season with a new top laner, Oner and the roster qualified as the second LCK seed for the 2025 Mid-Season Invitational after defeating Hanwha Life Esports 3–0 in the Road to MSI bracket. There, the team ultimately made it to their fifth MSI final in the organization's history, but fell short after losing to fellow LCK representative Gen.G 3–2 in a close series. In the second part of the newly revamped LCK season the team comfortably secured a spot in the 2025 LCK playoffs, where they qualified to the 2025 League of Legends World Championship after defeating Dplus KIA in round 2 of the lower bracket. The team qualified for the play-in stage of the World Championship as the fourth and final seed from the LCK, after losing to Gen.G 3–2 in round 3 of the lower bracket which ended their run in the LCK playoffs. At the World Championship, the team defeated Invictus Gaming 3–1 in the play-in stage to qualify for the Swiss stage. Despite a poor start to the Swiss stage, they qualified to the knockout stage with an overall 3–2 record after defeating 100 Thieves and Movistar KOI in the latter rounds. In the knockout stage, the team eliminated the last two remaining teams from China's LPL defeating Anyone's Legend in the quarterfinals in a close 3–2 scoreline, and Top Esports in the semifinals with a dominant 3–0 sweep. Oner and T1 defeated fellow LCK representatives KT Rolster with a 3–2 scoreline to win the organization's third consecutive Worlds title.
