Master Yi vs Karthus Matchup Summary

The Master Yi vs Karthus 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.

Understanding these matchup dynamics is essential for champion select decisions and in-game strategy when facing this lane opponent.
