Karthus vs Master Yi Matchup Summary

The Karthus vs Master Yi matchup is a decisive matchup in League of Legends ranked play. Based on 54 recent matches analyzed, Master Yi wins with a 59.3% win rate compared to Karthus's 40.7%, giving Master Yi a 18.5 percentage point advantage. Game phase dynamics play a critical role here: Karthus controls the early laning stage, but Master Yi outscales as the game goes longer. The matchup shifts dramatically depending on game length — Karthus needs to press advantages before Master Yi reaches their power spikes, while Master Yi should focus on safe farming and hitting key item breakpoints. 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.

During the early laning phase (first 15 minutes), Karthus has a meaningful 52.0% win rate, outperforming Master Yi by 4.0 percentage points. Karthus players should look to press this advantage through aggressive trades, wave priority, and early jungle coordination.

Master Yi is far superior in the late game (25+ minutes), boasting a 69.0% win rate — 37.9 points above Karthus. Extended games heavily favor Master Yi, whose kit and scaling make them a dominant force in team fights and objective control.

If Master Yi survives the laning phase without falling too far behind, the matchup flips in their favor.
