Key takeaways

- Both champions' overall Top win rates predict 49.7% for Olaf; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
- Olaf usually wins the lane: 347 gold ahead of Mordekaiser at 15 minutes on average (177 games with a 15-minute snapshot).
- Olaf players pick Plated Steelcaps much less often against Mordekaiser: 66.1% of their other Top games, 38.5% here.
How we calculate this
Games: ranked Solo/Duo and Flex games on the North America server from the patch shown. Remakes (games under 5 minutes) are excluded.
A game only counts when Olaf and Mordekaiser played the same position on opposite teams, so roaming, lane swaps within a team or a champion merely being in the same game never count as this matchup.
The 95% range is a Wilson score interval. Confidence comes from how wide that range is: within ±3 points is very high, ±5 high, ±8 moderate, anything wider low. Below 20 games a matchup is not classified at all.
Expected win rate combines both champions’ win rates in this lane (same games and filters) with the log5 formula: E = A(1−B) / (A(1−B) + B(1−A)). Matchup effect = observed − expected.
"What changes" compares Olaf's choices in this matchup with the same champion's other games in the same lane, and lists a change only when it is at least 3 points and statistically significant (two-proportion z-test, |z| ≥ 2, 20+ games).
Results are not split by rank: the sample per rank is too small for honest per-rank matchup numbers.

Against Mordekaiser
60.7% win rate · 28 games
Limited sample: 28 of 108 games finished this exact core, so treat it as an observation rather than a recommendation.
- Olaf usually completes Stridebreaker first, at 12.2 min (median of 101 games).
- Mordekaiser usually completes Rylai's Crystal Scepter first, at 12.3 min (median of 98 games).
- Skill priority: Q > E > W — the same as usual.
Builds are ranked by the lower edge of their win rate range, not the raw win rate, so a build seen in a handful of wins never outranks a proven one.
