Cassiopeia vs LeBlanc Counter Pick

Two of the harder champions in the game meet here — Cassiopeia at the maximum difficulty of 10, LeBlanc close behind at 9 — and the mid lane pairing goes to LeBlanc: 42.4% for Cassiopeia across 314 games on patch 16.13.1.

The deciding factor is mobility. Cassiopeia has no dash or blink in her kit and relies entirely on Serpentine Grace making her move speed bonuses more effective to create distance, while LeBlanc’s Distortion lets her dash to a location and then return to her starting point within a 4-second window — enough burst mobility to dive in, land damage, and escape before Cassiopeia’s poison can punish the approach. LeBlanc’s passive, Mirror Image, also grants a second of invisibility and spawns a decoy below 40% health, adding an extra layer of survivability Cassiopeia has to play around.

Ethereal Chains roots LeBlanc’s target after 1.5 seconds of contact and deals additional damage on the root, a combo that can lock Cassiopeia down mid-cast. Both champions run 30 magic resist and deal magic damage, so this isn’t a resistance-stacking problem — it’s a mobility mismatch between two high-skill mages. Full kits: Cassiopeia, LeBlanc.
