Master Yi vs Illaoi Matchup Summary

The Master Yi vs Illaoi matchup is a decisive matchup in League of Legends ranked play. Based on 10 recent matches analyzed, Illaoi wins with a 70.0% win rate compared to Master Yi's 30.0%, giving Illaoi a 40.0 percentage point advantage. Illaoi dominates at every stage — from early laning through late game team fights. This consistent advantage makes it difficult for Master Yi 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 Illaoi leads by 0.1s CC/min — a difference that heavily influences the outcome of trades and skirmishes. Illaoi has a strong advantage in this matchup. Master Yi players should play defensively, prioritize safe farming under tower, and look for opportunities created by jungle pressure or Illaoi 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.
