At a glance

Wind Wall blocks NOTHING that matters — Q is ground-cast, W is a zone, E is point-and-click. Ground his dash chain and fang him down.

Track: Yasuo's W — Wind Wall (25–17s cooldown). Blocks every projectile for its duration — hold your poke until it is spent.

Do

  • Drop W on his dash lane mid-engage
  • Fang through Wind Wall — it can't block them
  • R face-on when he commits the knockup

Don't

  • Burn W on poke spacing
  • Fight inside his wave at even HP
  • Pop R on a feint before the real commit

How to beat Yasuo as Cassiopeia: the early game

Yasuo's Wind Wall gives him real tools to neutralize your poke if he times it well, so early trades are more even than most matchups — vary your poke angles and don't throw single-target abilities into an obvious wall setup. He wants to dash in behind a blocked ability and all-in, so keep your Miasma up to slow his approach and punish the follow-up.
