Xayah vs Yasuo

Cast a spell before your autos: with Clean Cuts (passive), they pass through every target in their path and each leave a feather to call back.

Activate Deadly Plumage (W) before a trade: you gain attack speed, each auto fires a second blade, and hitting a champion makes you faster.

Position yourself so that Bladecaller (E) pulls your feathers back through your target: at least 3 feathers have to hit them to root them.

Cast Featherstorm (R) to dodge a decisive spell: you're untargetable for 1.5 seconds, then you leave a line of feathers to call back with Bladecaller (E).

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.
