Yasuo vs Lucian

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.

Punish him after an aggressive dash: Relentless Pursuit (E) has a 16 to 14 second cooldown, only reduced when his double shots hit.

Back off after each of his spells: Lightslinger (passive) doubles the next auto, so his damage comes in short bursts.

If your attack range beats his 500 units, poke him from outside it: he then has to use Relentless Pursuit (E) to get back on you.

If you survive the laning phase, play for time: Lucian is strongest early and loses impact once everyone has their items.
