Yasuo vs Miss Fortune

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.

Don't stay behind a low-health minion: if Double Up (Q) kills it, the bounce that hits you always crits.

Hit her regularly, even with a small hit: Strut (W) only grants her passive move speed after a few seconds without taking damage.

If you can engage, get on top of her: Miss Fortune has no dash or leap, only the speed from Strut (W).

If you have CC, save it for Bullet Time (R): she channels in place, and interrupting her cancels the remaining waves.
