Cassiopeia Counters

Looking for reliable Cassiopeia counters? The matchup numbers below come straight from current ranked games in the Mid role, not from tier-list guesswork. The toughest lane opponents at the moment are Vel’Koz, LeBlanc, Gragas: against them Cassiopeia posts its lowest win rates in the current data set. The single strongest counter is Vel’Koz, where Cassiopeia wins just 39.5% of 109 recorded games. On the flip side, Cassiopeia performs well into Aatrox, Gnar, Mordekaiser, making them safer picks to face.

Each card shows the win rate from Cassiopeia’s perspective and the number of games behind it — a matchup with tens of thousands of games is far more trustworthy than one with a few hundred. The Easy/Even/Hard labels are computed from those win rates (below 48% reads as Hard, above 52% as Easy); they are a reading aid, not a separate source stat. Data comes from ranked games at Emerald rank and above across all regions, currently on patch 16.13.1, and refreshes automatically every 48 hours, so the numbers move with the meta. Counters are only half the picture: check the current Cassiopeia build for the strongest items and runes, or the Cassiopeia champion page for abilities and full details.
