Yasuo vs Galio

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 after Justice Punch (E): it's his only dash, on an 11 to 7 second cooldown.

If you deal physical damage, lean on it in trades: the passive shield of Shield of Durand (W) only absorbs magic damage.

Leave the area while he charges Shield of Durand (W): the longer he charges, the longer and wider the taunt.

Before diving one of his allies, check where Galio is: Hero's Entrance (R) flies him in from long range to an allied champion, and his landing is a knock-up.
