How are champion matchup win rates calculated?

Win rates are calculated from thousands of ranked games in Emerald+ elo on the current patch. Data is sourced from OP.GG and updated regularly.

What does a 55% win rate matchup mean?

A 55% win rate means Champion 1 wins 55 out of every 100 games against Champion 2 in ranked. Anything above 52% is considered a favorable matchup.

Do matchup win rates change every patch?

Yes. Champion buffs, nerfs, item changes, and meta shifts can all affect matchup win rates. Our data updates with each new patch.

Should I always pick the counter champion?

Not necessarily. Comfort and experience on a champion often matter more than counter-picking, especially below Diamond. A 2-3% win rate difference is easily overcome by champion mastery.

What rank is the matchup data from?

All matchup data is sourced from Emerald+ ranked games to ensure the data reflects skilled play. Lower elo matchups can differ significantly.

How to Play This Matchup

Power Curve

Ahri is strongest mid game while Kassadin peaks late game. Play around your power window.

MR Priority

Both deal magic damage. An early Null-Magic Mantle or Mercury's Treads can swing the lane. Hexdrinker is also an option for AD champs.

Mirror Playstyle

Both champions play a burst style. The one with better execution and itemization wins. Focus on spacing and cooldown tracking.

Range Advantage

Ahri has range advantage. Kassadin should look for short trades when Ahri uses abilities on the wave. Freeze near your tower and wait for jungle help or an all-in window.

Exploit Ahri's Weakness

Ahri's main weakness: Tanks, sustain lanes, charm is dodgeable. Play around this to maximize your advantage.

Ahri Win Condition

Roam with R, pick off squishies with charm combo

Kassadin Win Condition

Survive to 16, R spam becomes uncatchable assassin

Kill Pressure vs Map Play

Ahri typically runs Ignite for kill pressure. Kassadin runs Teleport for map impact. Ahri needs to convert the combat advantage into kills before Kassadin outscales through TP plays.
