Key takeaways
- Current data slightly favors Senna, but the sample is too limited for a strong conclusion: Senna wins 55.5% of 211 games (95% range 48.7–62.0%).
- Both champions' overall Support win rates predict 54.1% for Senna; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
- Senna usually wins the lane: 710 gold ahead of Yuumi at 15 minutes on average (140 games with a 15-minute snapshot).
- Senna players pick Serpent's Fang far more often against Yuumi: 6.6% of their other Support games, 25.4% 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 Senna and Yuumi 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 Senna'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 Senna Build vs Yuumi
Usual Senna build (Support)
86.7% win rate · 15 games
Against Yuumi
Not enough matchup-specific build data: only 13 of 46 Senna games against Yuumi carried a complete build, which is too few to recommend an item path from. Use Senna's standard build instead.
- Senna usually completes Black Cleaver first, at 14.0 min (median of 69 games).
- Yuumi usually completes Mikael's Blessing first, at 12.0 min (median of 47 games).
- Skill priority: Q > W > E — 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.
