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

Early Aggression

Kalista needs to punish Zeri before they scale. Zone them off CS levels 1-5 and look for solo kills before first back. If Zeri reaches 2 items even, you're in trouble.

Armor Rush

Both champions deal physical damage. Whoever builds armor first (Plated Steelcaps, Bramble Vest) gets a huge advantage in trades.

Mirror Playstyle

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

Exploit Zeri's Weakness

Zeri's main weakness: Short range Q, weak early, needs R stacks. Play around this to maximize your advantage.

Kalista Win Condition

Rend stacks execute, R save/engage support, kite forever

Zeri Win Condition

R speed stacking, kite forever, scale into hypercarry
