Welcome to the tips, tricks and skillz required to go 0/11 every game.
The first step is to lock in Yasuo; after that, all you need to do is hope nobody dodges and congrats you have got into a game as Yasuo.

Pros:

Very annoying to enemy and ally players in the game
Has **** loads of damage
Lots and lots of mobility
Super high feeding capabilities
Smol health bar
Has a big sword
Is near unstoppable for the 1% of games he does not feed in

Cons:

Windwall doesn't block tower shots

Yasuo has so much in his kit that you wonder why the majority of Yasuo players feed on him, and the reason why is that the enemy knows the following tricks:

The first thing to do when you encounter a Yasuo player is to not try and outplay the Yasuo! Merely wait patiently and observe the Yasuo player in their natural habitat. You will get to witness, reasonably quickly, the Yasuo player successfully outplay themselves.

Passive:
Called Wanker of the Century

All critical strike chance is doubled that means you get the big boi damage

50% crit chance = 100% crits because maffs

10% less damage on crits cos BaLAncEe

When the big man moves about and **** he gets this thing called flow

When the flow is maxed, and you take damage from an enemy, you get a big shield

The shield is removed after the first bit of damage is dealt by an enemy. So an auto attack will remove it even though it doesn't deal the same damage as the shield blocks

Q:

Called Steel Beams can't melt jet fuel!!!

Stab enemies in the face with a spork dealing physical damage and applying on hit effects to the first enemy hit

Cooldown scales with attack speed

Hitting something with Q grants a stack of gathering storm, once you get 2 stacks you become Janna and throw a tornado in a chosen direction.

The tornado does the same amount of damage but knocks up enemies because Janna

Using Q directly after using E causes Yasuo to become a ballerina for a second and does a wee spin

Deals lots of damage because of two abilities at once

Is weaved in amongst auto attacks because you need something to do in that time otherwise, people will know you have no idea what you are doing

W:
Called Why the **** do I even play this game when this ******** exists

Yasuo creates a massive wave of wind (yes, the air) and magically it does **** like prevent every single ****ing projectile in the game from passing over it

Ashe ult = blocked

Ezreal ult = blocked

Ornn sends out thomas the dank engine = blocked

Nami ult = blocked

Auto attacks = blocked

Minion attacks = blocked

Fun in the game = blocked

My desire to carry on with this life = blocked

etc.

When you level it up you get a bigger wall, so big Trump has wet dreams about it

E:
Called Sliding into DMs only to get rejected for being a nice guy. **** you Brenda you ****!

Dash into champions dealing magic damage and marking for few seconds

Can't dash through marked enemies

Dash has almost no cooldown because BaLEns

Dashing also gives flow because movement

Damage increases by 25% per cast up to 50%

This is one of the how to outplay yourself abilities

R:
Called Inting in style

Yasuo can only ult when enemies are knocked up

This can be any knock up by you, your teammates, baron, the blast plant, and a bunch of other ****

When cast:

Yasuo gracefully leaps to the enemy shouting "Love me senpai!" before getting rejected and in a fit of despair slaps them a bunch of times before smashing that *** into the ground dealing tons of damage

His flow bar is immediately filled meaning extra shield

For the next 15 seconds he gets 50% bonus armour penetration on his critical strikes because whATs a TaNk

Start the game with a Doran's Blade and the run it down mid.

Once you get the core items you start doing the big boi damage

Go in for trades when the enemies abilities are on cooldown, usually when the clear minion waves with abilities

Enemy minions are your allies, try to fight when there are at least 2 enemy minions there for you to dash to

If you feed, don't worry about it, it is expected of you

Pick on the weak, fair fighting and sportsmanship is not what League of Legends is about!

BEST OF LUCK ON THE RIFT!
