Karmine Corp Blue advanced to the EMEA Masters 2025 Summer finals with a brutal three-zero sweep of Los Ratones in the semifinals. All three games ended in under 30 minutes, with KCB building early leads and closing out before LR could reach their comfort zone.
The numbers paint a stark picture. Across three games, Los Ratones secured only six kills, one dragon, and four towers. Game times clocked in at 27, 27, and 25 minutes. KCB established gold leads of 3,000 to 5,000 by the mid-game in each match and never looked back.
Los Ratones never found their footing. The team built its identity around macro-focused mid and late-game teamfighting, but KCB denied them those opportunities entirely. Early-game pressure from KCB’s jungle and bot lane locked down objectives and snowballed advantages before LR could stabilize.
Draft prep played a major role. According to post-match analysis from the French broadcast, KCB prioritized banning Xayah and Rakan—comfort picks that have anchored LR’s bot lane throughout the tournament. The academy squad came in with a clear gameplan: play standard, secure early leads, and don’t throw teamfights.
KCB’s engage-heavy compositions punished LR in the bot lane repeatedly. Picks like Nautilus, Alistar, and Rell set the tone, creating kill pressure and objective control that LR couldn’t answer. With their bot lane under siege and jungle pathing compromised, Los Ratones fell behind in every lane phase.
Los Ratones entered the tournament as one of the most-watched teams in European Regional League competition. The roster features well-known personalities including Thebausffs, Nemesis, and Rekkles, combining competitive play with heavy streaming content. Their scrims draw thousands of viewers and their playstyle emphasizes smart rotations and teamfight execution.
But early-game fragility has been LR’s persistent weakness. Against opponents willing to give them space, they’ve crafted comebacks and clutch fights. KCB gave them nothing. The academy team executed their tempo cleanly across all three games, closing before Los Ratones could reach power spikes or find advantageous fights.
