Yasuo vs Fiora

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.

Take short trades: each Vital she hits with Duelist's Dance (passive) heals her and speeds her up.

If you have CC, wait until Riposte (W) is used: if it parries an immobilizing effect, her stab stuns you instead of slowing you.

Take a trade when Lunge (Q) has just whiffed: without an enemy hit, its cooldown isn't reduced, and it's her only dash.

Answer her split push with two players rather than alone: in a duel, Grand Challenge (R) reveals four Vitals and speeds her up near her target.
