Lim "Violet" Doo-sung began his career as an AD carry when he joined Incredible Miracle 1 in August of 2013. His first season of OGN was at HOT6iX Champions Spring 2014 where they placed third in their group and missed the playoffs. Violet left the team in May to join MKZ. MKZ competed in HOT6iX Champions Summer 2014 but they failed to win a single game and finished the tournament tied for last place. Violet competed in this tournament as primarily a support player but he played one game as an AD carry. MKZ was picked up by Xenics Storm in July. The team did not play tournaments together before disbanding sometime before the organization rebranded to Xenics.
MKZ reformed in March of 2015 and played in Challengers Korea Spring 2015 Series 2 where they ended in third after losing 3-0 to Xenics and Winners. MKZ also competed in Challengers Korea Summer 2015 but they ended in last with a 2-8 record. Violet primarily played as a top laner for MKZ at this time though he did play a game in mid lane and a game as an AD carry.
