Kassadin vs Yasuo Counter Pick

Wind Wall blocks all enemy projectiles for four seconds, and it is why many mid matchups against Yasuo start uphill. Kassadin is an exception: Riftwalk is a teleport, Force Pulse a cone, Nether Blade an empowered basic attack, and Null Sphere a targeted orb rather than a missile. Very little of that is a projectile a wall can stop. Across 1,179 games on patch 16.13.1 — a sample large enough to be stable — Kassadin returns 53.9%.

Yasuo is rated 10 for difficulty, the top of the scale, and the rating is earned. Way of the Wanderer builds a shield while he moves and raises his critical strike chance, Steel Tempest fires a whirlwind at two stacks, and Sweeping Blade dashes through enemies but cannot be recast on the same target, so his engage depends on minion positions. Flow replaces a mana bar entirely, removing the resource pressure Kassadin lives under.

His damage is physical, so Void Stone contributes nothing early, and the numbers favour him there: 32 armor at level 1 against 21, 175 attack range against 150, 345 movement speed against 335. After level 6, Last Breath needs an airborne target that Kassadin never supplies, and 2,567 health against 2,460 survives a full combo.
