Yasuo vs Naafiri

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.

Dodge Darkin Daggers (Q): her pack leaps onto the first champion hit, and the second dagger hits harder if you're already bleeding.

If you have AoE spells, hit her pack too: each packmate killed lowers her damage. Do it before Eviscerate (E) calls them back and heals them.

Save your targeted spells for after The Call of the Pack (W): for a brief moment, she and her pack are untargetable.

Avoid crossing the map alone against her: Hounds' Pursuit (R) lets her dash onto a champion from range, and a takedown lets her recast it.
