Yasuo vs Ezreal

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.

Stay behind your minions: Mystic Shot (Q) hits the first enemy, and each time it hits you, all his cooldowns go down.

Go all-in when he has used Arcane Shift (E) to move forward: it's his only escape, on a 26 to 14 second cooldown.

Look for head-on teamfights, behind your frontline: Mystic Shot (Q) stops on the first enemy hit, and Essence Flux (W) on the first champion.

At low health, beware of Trueshot Barrage (R) even far from him: the shot crosses the whole map and hits every unit in its line.
