- Current data slightly favors Cassiopeia, but the sample is too limited for a strong conclusion: Syndra wins 48.2% of 83 games (95% range 37.8–58.8%).

- Neither side reliably wins the lane: the average gold difference at 15 minutes is 37, within the margin of error (62 games).
- Syndra players pick Luden's Echo much less often against Cassiopeia: 51.2% of their other Mid games, 34.9% 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 Syndra and Cassiopeia 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 Syndra'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 Syndra Build vs Cassiopeia
Usual Syndra build (Mid)
86.2% win rate · 29 games
Against Cassiopeia
Not enough matchup-specific build data: only 7 of 38 Syndra games against Cassiopeia carried a complete build, which is too few to recommend an item path from. Use Syndra's standard build instead.
- Syndra usually completes Blackfire Torch first, at 11.8 min (median of 35 games).
- Cassiopeia usually completes Rod of Ages first, at 11.5 min (median of 46 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.
