What the Data Means
Sejuani against Amumu (Jungle) is tracked here with real ranked data rather than theorycraft. Across 229 recorded games on patch 16.13.1, Sejuani wins 43.7% of the time against Amumu. That places Amumu among Sejuani’s toughest opponents right now — the win rate sits clearly below the break-even line, which is exactly why this matchup is flagged as a counter.
When reading this matchup, weigh the sample size as much as the percentage — bigger samples mean the number is less likely to swing with the next patch.
