Yasuo vs Aurora

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 a trade once Across the Veil (W) is used: it's her spell to vanish, on a 22 to 18 second cooldown unless she takes part in a kill.

Take short trades: every spell or auto that hits you releases a spirit that heals her, through Spirit Abjuration (passive).

Don't fight inside Between Worlds (R): she teleports from edge to edge, and crossing the edge slows you. Get out early, with a dash if you have one.
