Matchups
Every matchupHow to read this
Master Yi’s win rate against each champion picked into it in the lane opposite: its hardest matchups, then its easiest. The small number is the matchup’s own effect on Master Yi, the part not explained by either champion’s strength.
Hardest for Master Yi
Lane leads and team bans
What Master Yi’s team bans
Champions a team bans more often when it has Master Yi than the other team does in the same games (467,709 games). The other team banned before Master Yi was picked, so the gap is the ban spent because Master Yi was coming — a sign players see these as counters. Riot does not say which player cast a ban, so this is the team’s choice.

These numbers describe, they do not prove. Each rate is Master Yi’s record when its player chose that option, pulled toward Master Yi’s own rate by 100 games of prior so a small sample cannot look like a discovery. An uncommon page often wins more because experts run it, and they would win on any page, so only a choice taken in at least 10% of games can be recommended, and spells and keystones are ranked by how the SAME players do with them against the usual choice, not by the raw rate; rarer ones are listed with their numbers and labeled. The build line (opening buy, the two key items in the order they are finished, boots or the support upgrade) is advice in the same sense: how Master Yi does when built that way.
The learning curve

How much knowing Master Yi pays
Players on their Mastery band win 8.0 points more on Master Yi than first-timers do: #26 of 173 champions for how much mastery pays.
At 300k+ mastery points, Master Yi players win 52.9%: #43 of 173 champions for where mastery ends up. The curve is still rising there: its fitted ceiling of about 54.4% lies beyond the data and is an estimate, not a measurement.
Master YiDots are the six mastery bands, placed at their mastery points. The line is the best-fitting curve that rises and levels off.
This is not a promise about your next game. Players do not reach a mastery band in a random order, and a champion someone loses on tends to get dropped before it reaches the high bands — so the right-hand side of every curve is partly survivors, not only practice.
