Smolder vs Yasuo

Last-hit minions with Super Scorcher Breath (Q): each kill with the spell gives you a Dragon Practice (passive) stack, which empowers your basic spells.

Poke with Achooo! (W): the sneeze slows, explodes on champions hit, and each champion hit gives you a Dragon Practice stack.

Build enough stacks for the final tier of Super Scorcher Breath (Q): it burns its target, and kills a champion who drops below a health threshold.

Escape or reposition with Flap, Flap, Flap (E): you fly over obstacles, bombarding the enemy with the lowest health.

Cast MMOOOMMMM! (R) to finish or slow from far away: the center of the breath hits harder and slows, and if it hits you, your mom heals you.

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.
