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

Survive to Scale

Shaco will try to bully you early. Give up CS if needed Ã¢â‚¬â€ your job is to not die. Karthus outscales hard after 2 items. Play for farm, not fights.

Mixed Resistances

Karthus deals AP damage while Shaco deals AD. Build resistances accordingly Ã¢â‚¬â€ don't stack the wrong type.

Sustained vs Burst

Shaco wants to combo and disengage. Karthus wins extended trades. Don't let Shaco get a clean rotation Ã¢â‚¬â€ force long fights where sustain wins.

Range Advantage

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

Exploit Shaco's Weakness

Shaco's main weakness: Falls off late, team needs to play around boxes, squishy. Play around this to maximize your advantage.

Karthus Win Condition

R global damage, passive keeps dealing damage after death

Shaco Win Condition

Early cheese ganks, box traps, clone mind games
