You are about to look at one of the most crit heavy champions in the game. He benefits better from Crit than any other champion in the League. If you want to, you could kind of look at him as a melee version of Vayne.

They're pretty much standard top lane runes except for the Quints. You want the Crit Damage Quints for the fact that you have an incredibly high crit chance rate, so it's bound to work for you.

A good deal of people don't get a Randuin's Omen on Yasuo, but I'm really fond of the item on him. It gives him the chance to live longer in a fight, and you can use it to either retreat from an enemy, or to catch up to an enemy and STRIKE THEM DOWN.

I like to take Teleport instead of Ignite on him so I can use it to do some hardcore pushing in any lane.

Since you're gonna be fighting in the top lane for a decent portion of your levels, you don't really need Wind Wall early on.
If you're facing a ranged opponent, just replace the 2nd level in Sweeping Blade with a Wind Wall rank.

Pros:
Hits like a truck
Crit is amazing on him
Highly mobile when in combat.

Cons:
Really squishy
Can be shutdown in a real bad way
Ultimate can be unreliable at times

It can be extremely beneficial to have a team composition to compliment Yasuo's Ultimate ability. With a knock up team composition, you are able to pop your ultimate with next to no problem.3
