Yasuo vs Akali

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 Twilight Shroud (W) is used: she can't vanish again until its 20 to 16 second cooldown is over.

Play hard before she hits level 6: without Perfect Execution (R), her only spell to get back on you is Shuriken Flip (E), on a 16 to 10 second cooldown.

If you have AoE spells or skillshots, throw them into the Twilight Shroud (W) smoke: they hit her even while she's invisible, whereas targeted spells can't be cast on her.

Take a trade when she has just cast Five Point Strike (Q) several times: each cast costs 110 to 70 energy depending on rank, from a base pool of 200.

Hit her right after the first dash of Perfect Execution (R): she has to wait a moment before she can cast the second.
