Pro:
Great fighter
Blocks with his W(wind wall)
doesn't use mana
Has a shield
His Ultimate has a short cooldown, and it has long range
You can use his E(Sweeping blade) to get to your enemy

Con:
Cant use ult all the time
doesn't have an awesome escape
Really hard to master.

Passive: Way of the wanderer: This passive is pretty cool because it can let you get poked and not loose as much health. it also gives you a lot of critical strike. Make sure to get a lot of critical strike when playing Yasuo.


Steel Tempest: I love this spell. It is an amazing farming spell. it also helps your ultimate, and it does a lot of damage. The faster you stack it up, the quicker you can use your ult. So when you stack up your q and you use it again, it will shoot out a whirlwind that knocks up your enemy.


Wind wall: I like this spell becuase it can block any type of spell but a turret shot. I still havent mastered it but i'm getting the hang of it. It also shortens the cd on your E ( Sweeping blade) which ill talk about in a bit.


Sweeping blade: This spell is great to get to your enemy. it doesn't have that much damage, but the cooldown is very short. The only thing about it that kinda takes a long time is the cooldown on using it on one person. ( you can only use it on one person for a short period of time.


Last Breath: This is the ultimate. it is very powerful against low health champions. You can only use it if the enemy gets knocked up. Then you fly to then and slice them in the air and then smash them on the floor. It does a lot of damage.

Some MATCH UPS that are good for Yasuo is:

Cho gath, janna, jarven, zyra, xin, zac, draven, volibear, lee sin, lulu, malphite, orianna, jayce, maokai, shavanna, blitzcrank, diana, nami, nautilus, riven, hecarim, gragas, fizz, alistar, rammus, thresh sejuani, vi, darius, wukong, quinn, singed, vayne.



If i miss any, pm me. :)

Flash: I like flash because it helps you secure the kill and get away when about to die.


Ignite: I use ignite because it also can secure the kill. it does a lot of damage for killing.


Ghost: you can use ghost for your passive( Makes a shield when you fill it up from running) but other than that, i still recommend flash and ignite.

Ninja Tabi boots: i like these because it gives you armor and it also give you enough speed.


Infinity edge: i use this because it gives you a lot of damage and it also gives you a lot of critical strike for you spells and auto attacking.


Statikk shiv: I use this for its passive( when you auto attack or do nothing, it powers up until it hits 100%, when it does that, your next basic attack or spell sets off a lightning strike that hits up to 4 enemys or minions.


Youmuus ghostblade: This item is great on Yasuo, it helps your passive on statikk shiv with the attack speed it gives you, it also gives you movement speed that will help your passive. it also gives critical strike and attack damage.


Trinity force: I Cant really explain this, all this item does is gives you a lot of damage, health, critical strike, attack speed, and a passive that does extra damage on an auto attack. ( this item is amazing).


Randuins omen: This item is his main tank item. he need health because he is kinda squishy. It also gives armor and an active that slows the attack speed of enemys that are around you.

Other good items are at my item build above, check them out if you dont like mine! :P

Some things you can so is to use your Q(Steel tempest) to farm and poke.( remember it crits so get a lot of crit items.
Another thing that is good about Yasuo, is his W(Wind Wall) This is good to block spell that can damage you or slow you ect. it also make the cooldown on your E so you can dash on it quicker.
Also your E(Sweeping blade) also very good at catching up to your champion or to farm.
And least of all, just use your ult to help your jungle and use in laning phase.
