All seasons combined — the current-season read is further up. How this champion is actually used: which role, which side of the map, and whether it shows up more in playoffs than in regular season.

Bars show pick volume, the line shows win rate. The dashed line marks 50%.

Across all seasons (2011–2026): a single season does not supply enough shared games. Allies seen at least 25 times alongside Sion. The gap is measured against its own 48.5% average, not against 50%. The Role column is the one held by the ally.
