Karthus vs Master Yi Matchup Summary

The Karthus vs Master Yi matchup is a decisive matchup in League of Legends ranked play. Based on 37 recent matches analyzed, Master Yi wins with a 62.2% win rate compared to Karthus's 37.8%, giving Master Yi a 24.3 percentage point advantage. Master Yi dominates at every stage — from early laning through late game team fights. This consistent advantage makes it difficult for Karthus players to find favorable windows, so team-dependent strategies and avoiding solo confrontations are essential. The most significant statistical gap is in crowd control, where Karthus leads by 0.3s CC/min — a difference that heavily influences the outcome of trades and skirmishes. Master Yi has a strong advantage in this matchup. Karthus players should play defensively, prioritize safe farming under tower, and look for opportunities created by jungle pressure or Master Yi overextending. Avoid prolonged trades and wait for team fights where positioning and coordination matter more. Understanding these matchup dynamics is essential for champion select decisions and in-game strategy when facing this lane opponent.
