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

Janna is strongest mid game while Nautilus peaks early 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.

Range Advantage

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

Exploit Nautilus's Weakness

Nautilus's main weakness: Poke, disengage, hook is slow. Play around this to maximize your advantage.

Janna Win Condition

Disengage with Q+R, shield ADC, peel for carries

Nautilus Win Condition

Hook + passive root + R point-and-click lockdown
