Cho "Mata" Se-hyeong joined MVP Ozone as a support in February of 2013. In his first season as a professional player, Ozone won the OLYMPUS Champions Spring 2013 finals 3-0 against CJ Entus Blaze in one of the biggest upsets in League of Legends history. The team did fairly well in HOT6iX Champions Summer 2013, placing third after losing 3-1 to SK Telecom T1 but beating CJ Entus Frost 3-2 in the third place match. Ozone earned enough circuit points to qualify automatically to the Season 3 World Championship as the second seed from Korea. A week later, both Ozone and their sister team, MVP Blue, were bought by the Samsung organization, forming Samsung Galaxy Ozone and Samsung Galaxy Blue. Ozone disappointed at worlds, dropping out in groups after losing a tiebreaker to Gambit Gaming.
Ozone began the new year with PANDORA.TV Champions Winter 2013-2014 where they made it to the finals but were swept by the undefeated SKT K to end in second place overall. They placed similarly at HOT6iX Champions Spring 2014, losing 3-1 to Blue in the semis but beating Blaze 3-2 in the third place match to finish in third. A month later, Ozone changed their name to Samsung White. HOT6iX Champions Summer 2014 was not much different for the team. They lost 3-1 again to Blue in the semis but they swept SK Telecom T1 S in the third place match. They were forced to play a tiebreaker against SKT K for the second Korean seed at the 2014 Season World Championship and they swept them 3-0 for the spot. White came into worlds as the heavy favorites and impressed, only dropping two games the whole tournament. They played a fairly one-sided final against Star Horn Royal Club and took the title with a 3-1 victory with Mata managing to earn himself the the MVP title for the tournament. On October 25th 2014, Mata announced that he was leaving the Samsung organization and was considering his options. On November 27th, 2014, DanDy, Skatch, Heart and Mata all together joined Vici Stand Gaming.
At the beginning of the year, Mata and DanDy were moved to the main Vici Gaming roster to compete in the 2015 LPL Spring Regular Season. They competed in the 2015 Demacia Cup Spring Season first and fell in the round of 16 with a 3-0 loss to Invictus Gaming. They ended in fourth in the LPL regular season but lost in the first round of the 2015 LPL Spring Playoffs, dropping 3-1 to IG. Vici played in the 2015 Demacia Cup Summer Season, making it to the quarterfinals but forfeiting their series against IG. During the 2015 LPL Summer Regular Season, they ended in sixth in the LPL and made it to the quarterfinals of the 2015 LPL Summer Playoffs but Vici lost 3-2 here to IG.
Despite multiple rumors that Mata would return to Korea, likely to play on Incredible Miracle, Mata stayed in China for the 2016 season, moving to Royal Never Give Up. Royal Never Give Up were invited to IEM Katowice in March 2016 where they finished first in their group beating both Origen and Ever. However, they were defeated 1 - 2 by Fnatic in the playoffs bracket, placing third along with Team Solo Mid.
