KT Rolster have signed jungler Lee "Rush" Yoon-jae and mid laner Soon "UcaL" Woo-hyeon, a former member of their training team. They have also brought on former Giants Gaming player Son "S0NSTAR" Seung-ik as coach.
This will be Rush's first appearance on an LCK team after spending his entire career in the NA LCS. He signed with LMQ shortly before it rebranded to Team Impulse and went on to play for Cloud9. Rush did not play for any team during the 2017 season, and was replaced on C9 by Juan "Contractz" Garcia.
UcaL first joined KT as a trainee in May, and has now been promoted to the main roster, where he'll join mid laners Heo "PawN" Won-seok and Kim "Ssun" Tae-yang. UcaL is considered to be an extremely promising mid lane prospect.
S0NSTAR last played as a professional player for Giants Gaming in Europe, then coached for that team. He last coached Team AURORA in Turkey, which he helped place 3rd-4th in the 2017 TCL Summer Playoffs.
