- Current data slightly favors Kayn, but the sample is too limited for a strong conclusion: Rek'Sai wins 44.3% of 97 games (95% range 34.8–54.2%).

- Neither side reliably wins the lane: the average gold difference at 15 minutes is 205, within the margin of error (48 games).

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 Rek'Sai and Kayn 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 Rek'Sai'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.

Best Rek'Sai Build vs Kayn
Usual Rek'Sai build (Jungle)
62.8% win rate · 129 games
Against Kayn
Not enough matchup-specific build data: only 3 of 25 Rek'Sai games against Kayn carried a complete build, which is too few to recommend an item path from. Use Rek'Sai's standard build instead.
- Rek'Sai usually completes Scorchclaw Pup first, at 0.1 min (median of 41 games).
- Kayn usually completes Scorchclaw Pup first, at 0.2 min (median of 22 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.
