Caitlyn vs Yasuo

Place Yordle Snap Trap (W) in brushes and in their path: a champion who steps on one is rooted, and revealed to you for 3 seconds.

Chain 90 Caliber Net (E) and Yordle Snap Trap (W) under the slowed target: each champion netted or trapped grants you a double-range Headshot (passive).

Fire Piltover Peacemaker (Q) at a champion caught in your trap: they take full damage, even if the shot passed through a minion first.

Save Ace in the Hole (R) to finish a low-health target that's fleeing: another enemy champion can block the shot, so fire when no one is covering them.

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.
