Talon vs Yasuo

Apply three Blade's End (passive) stacks by hitting with your spells, then strike with an auto: the target starts bleeding and takes heavy damage over time.

Cast Noxian Diplomacy (Q) in melee range when you can: instead of the leap, it lands a critical strike. If it kills, it heals you and comes back faster.

During Shadow Assault (R), break invisibility with an auto or Noxian Diplomacy (Q): the blades then converge on your target instead of coming back to you.

Push your wave, then roam by vaulting walls with Assassin's Path (E): the spell comes back fast, but you can only cross the same wall again after a long delay.

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.
