Azir vs Yasuo

Place your Arise! (W) soldiers so their spear thrust goes through the wave and your opponent: it hits every enemy in a line.

To escape, cast Shifting Sands (E) toward a soldier behind you: the spell shields you, but stops on the first enemy champion in its path.

To get behind your target, cast Conquering Sands (Q) during the Shifting Sands (E) dash to a soldier. Emperor's Divide (R) then knocks them back toward your team.

Cast Emperor's Divide (R) between your team and those charging at it: the soldiers knock them back, then stay as a wall that blocks the way.

Hit him with a cheap attack to trigger the Way of the Wanderer (passive) shield, then start the real trade: otherwise, it absorbs your best damage.

If you have projectiles, save them for after Wind Wall (W): it blocks them all for 4 seconds, on a 25 to 17 second cooldown. Other spells go through it.

Don't stand right behind your minions: each one gives him a target for Sweeping Blade (E), and he gets closer to you with every dash.

Get out of the line of his whirlwind, the third Steel Tempest (Q): without a knock-up, he can't cast Last Breath (R).

Judge his threat by his crit items more than his level: Way of the Wanderer (passive) raises his critical strike chance, so each crit item does more for him.
