Jhin vs Yasuo

Save your 4th shot to trade: Whisper (passive) always makes it a critical strike with bonus damage, and each crit gives you move speed.

Fire Deadly Flourish (W) right after you or an ally hit the target: they're then rooted, and you gain move speed.

Place Captive Audience (E) in brush and along your escape path: the trap is invisible, slows the enemy who steps on it, then explodes.

Save the 4th shot of Curtain Call (R) to finish someone off: each bullet slows and hits harder on a wounded target, and the 4th is a critical strike.

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.
