The champion similarity map
“Who else should I play?” answered two different ways, then blended and drawn as a network.
Look up one champion
By kit
Similar toolset: range, damage type, crowd control, durability and role.
Overall match
Kit and co-play blended evenly — the pick to lead with.
By player co-play
Picked up by the same players, weighted by mastery and how recently they played it.
How to read this
Kit and co-play measure different things and only partly agree (13% overlap in their own top-5 lists): a kit match plays similarly, a co-play match is favored by the same kind of player, and the two can point at very different champions.
How this is measured
By kit: every champion's win rate, damage split, crowd control, range and role shares, pooled across every game and compared by cosine similarity. This finds mechanical twins — Aatrox next to Renekton — from the toolset alone, with no idea who actually plays either one.
By player co-play: which champions the same real players pick up, weighted by mastery points and how recently they played each one, computed across millions of accounts without ever looking at who any individual player is. This finds Morgana next to Lux — different kits entirely, but the same kind of player gravitates to both.
Overall match: the two blended evenly into one score. It is the pick to lead with, because either signal alone throws away real information the other one has: the two lists only overlap 13% at the top.
What actually showed up
Morgana's kit alone points at Brand and Zyra — other ranged mages with a similar burst-and-poke profile. But her real co-play neighbor, by a wide margin, is Lux: different kit, same kind of player, both built around landing a slow projectile root and following it up. The blended score pulls Lux into Morgana's top 3 where kit alone never would have. Compare that to Sett and Darius, where kit says they are nearly identical bruisers — and co-play agrees, because the same players who main one usually play the other.

How to read this
Every champion we ranked, connected to its 5 closest overall matches and colored by cluster. Champions that are alike sit close together. Hover a line to see where that pair sits on each signal separately — which is where the Morgana-and-Lux case actually shows up: Lux is Morgana's #1 co-play match but only her #7 by kit, so co-play is what pulled the two together.
