Who does Kassadin work with?

Delta in wins per 100 games against Kassadin's own average, the 8 best first. The bar under each figure draws that row's own 95% range on one scale, from 9.2 wins per 100 games below Kassadin's own average on the left to 8.8 above it on the right. The tick is our estimate, the short line is zero, and a hatched bar is one whose range covers zero or spans most of the scale: those games do not pin the pair down.

A pair needs 50 games together before it is estimated, and each estimate is pulled toward Kassadin's own average first, so a thin duo cannot crown itself. The verdict reads the delta range: beats only when the whole range clears zero. A delta bar that covers zero stays stone: unclear yet. Teammate pairs share fewer games than lane opponents, so this list runs shorter than the counters page.

142 more teammates, with 3,245 games between them, sit under the pair floor: counted, not listed.

What a delta cannot prove

A delta is not proof: the players who queue together differ from the players who do not, and nothing here holds that still.
