mid
Cassiopeia's WR when this ally plays mid. Sort ↓ Score for best synergies, ↑ for worst.
Synergy score from Cassiopeia's perspective. Per-result-set z-score (mean 0, SD 1) of the weighted composite 0.70·z(delta) + 0.20·z(games) + 0.10·z(WR). Positive = ally helps Cassiopeia, negative = ally drags Cassiopeia down. Same shape as the item synergy / counter pick / duo rankings + matchup tables.Cassiopeia's Bayesian-smoothed win rate when paired with this ally.Bidirectional synergy delta: avg of Cassiopeia's gain over their baseline and the ally's gain over theirs. High = both benefit from the pairing. Hover a row for the per-side breakdown.Number of games played together.

Worst MatchupⓘWorst lane matchup WR minus this champion's own baseline WR, both Bayesian-smoothed. Tail complement to Matchup Spread — captures champions punished by a small number of extremely spiky lanes that MAD averages out. Closer to 0 = no truly bad lanes (safer blind pick). Min 30 games per opponent, ≥5 well-sampled opponents.
