Yasuo vs Gangplank

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.

Destroy his kegs before he does: a Powder Keg (E) destroyed by an enemy is defused, and each keg loses health over time.

If you can engage, go all-in: his kit has no dash to escape.

If your team has several CCs, don't use them all at once: Remove Scurvy (W) cleanses all his CC, then has a 22 to 14 second cooldown.

In teamfights, get out of his kegs' area: each Powder Keg (E) explosion deals the damage of the attack that set it off, ignores part of your armor and slows you.
