Kim "Ace" Ji-hoon joined Samsung Galaxy in February of 2015 as one of their mid laners. He was given the starting mid lane position alongside their old mid laner, BlisS. The team played in SBENU Champions Spring 2015 but placed last and were forced to play in the 2015 Champions Summer Promotion. Samsung qualified for SBENU Champions Summer 2015 when they placed first in their group by beating Prime Clan and Xenics. Crown joined the team soon after to share the mid lane position with both Ace and BlisS. Samsung placed seventh during the regular season and missed playoffs but they qualified for the next season of LCK.
Samsung competed in the 2015 LoL KeSPA Cup where they were placed against Ever in the first round. To the surprise of many, Samsung was quickly dispatched 2-0. Ace did not compete at this tournament. Ace left the team on November 30th.
