Key takeaways
- Current data slightly favors Janna, but the sample is too limited for a strong conclusion: Poppy wins 48.4% of 31 games (95% range 32.0–65.2%).
- Both champions' overall Support win rates predict 48.0% for Poppy; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
- Neither side reliably wins the lane: the average gold difference at 15 minutes is 66, within the margin of error (31 games).
- Poppy players pick Health Potion + Health Potion far more often against Janna: 30.8% of their other Support games, 53.3% 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 Poppy and Janna 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 Poppy'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 Poppy Build vs Janna
Usual Poppy build (Support)
55.6% win rate · 90 games
Against Janna
Not enough matchup-specific build data: only 3 of 15 Poppy games against Janna carried a complete build, which is too few to recommend an item path from. Use Poppy's standard build instead.
- Janna usually completes Moonstone Renewer first, at 13.6 min (median of 20 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.
