Yasuo vs Aphelios

Hit twice with Steel Tempest (Q), on minions if needed, to charge the whirlwind. Cast it during Sweeping Blade (E): the strike becomes a circle.

Keep moving before taking a trade: Way of the Wanderer (passive) builds your shield while you move, and it triggers on the first hit you take.

Chain Sweeping Blade (E) on different targets to reposition or dodge: each target has its own cooldown, so the spell comes back almost instantly.

Save Wind Wall (W) for a projectile that decides the teamfight, like Jinx's ult, rather than for poke: it blocks for 4 seconds, on a 25 to 17 second cooldown.

Watch for your allies' knock-ups: Last Breath (R) can be cast on any airborne champion, whether the knock-up comes from your whirlwind or Malphite's ult.

Back off when he holds Gravitum and has slowed you: Weapon Abilities (Q) with the cannon roots every enemy that weapon has slowed.

If you can engage, go for him when his support drifts away: his kit has no dash, and only Severum makes him run faster.

Spread out from your allies when he has Moonlight Vigil (R): the blast explodes on the first champion hit, damages those nearby, then he attacks each of them.

When he deploys the Crescendum sentry with Weapon Abilities (Q), leave its area: it attacks you with his off-hand weapon.
