Welcome to my way of building and playing Yasuo. I am a Platinum player and found Yasuo to be one of my favorite champions, even after his "nerfs". I enjoy playing Yasuo as he does indeed require more knowledge to play such as using his abilities correctly, and knowing when to use his ultimate.

What is Yasuo? He is a mobile fighter who deals a huge amount of upfront damage due to the items which sync perfectly with his kit. He can 3 shot an adc with ease with the build above. He can clear minions at exceptional speeds, being able to use his Sweeping Blade combined with Steel Tempest to one shot half a minion wave, basic attack, repeat for the next part to clear it in around 2 seconds. With [statikk shiv] Yasuo can push like a monster due to Sweeping Blade counting as movement for the charges. Yasuo is deceptively tanky thanks to his shield which late game shields for a whopping 470 damage, which gets reproced if he lands his ultimate. Yasuo has one of the best team fight ultimates in the game as it is a knock up, meaning it will always have the same duration regardless of tenacity, Last Breath even allows Yasuo to IGNORE 50% of all champions armor.

Yasuo in my eyes is essentially a melee adc with some hard cc, thus he can effectively engage fights, and do huge amounts of damage. He excels in burst and dps so regardless if someones squishy, or tanky, they will die.
