LANE:
In the top lane I normally start Q level 1 since it can be dangerous to dash into enemy top laners at lvl. 1 since most of them are AD and have a close range ability that can win them the trade heavily (Ex. Darius). Since most matchups are melee, I wait till they walk up to kill a creep and Q them through the wave. I try to get Level 2 first and then use my E Q together to dash onto them and get off as much damage as i can. Normally I can win the trade very heavily especially if they are still level 1. I just continue to do this throughout the early game of lane, and adjust to the matchup, or ganks if necessary.

Teamfights:
Mid game teamfights or skirmishes are really about using your allies knockups or "airborne" abilities to your advantage to get off a good ult. If your allies don't have any abilities that synergize with your allies then it's up to you to build up stacks during or before the fight starts. Most of the time you want to get a knockup onto the enemy mid laner or ADC and do your best to negate their damage by using your Windwall for the ADC's auto attacks or any other important ranged abilities. Your job as Tank/Damage Yasuo is to kill their carries while trying to survive as long as you can. To survive you're going to need to use your Ult and E to your highest capability. Mid game teamfights are very important for snowballing and getting control of objectives, and a good Yasuo can turn a teamfight easily.

Late Game Teamfights:
Late game teamfights are all about 1 shotting their ADC or Mid laner, while using your Windwall to completely negate their ADC's damage. Also you can play Tank/Damage Yasuo as a peel top laner and when the enemy team engages you use your W to delay their engage, build up stacks and then engage with an E Q combo or Knockup from your Tornado or an Allie's ability. Since you should have at least 2 tank items at this point, you will be really hard to kill and should be able to at least get a lot of damage off or take out a carry or two for your team. If you can do this, or even live while doing this, you can win late game teamfights easily.

Hi, my name is Dylan and my current account name is Urke. I'm a Yasuo main who peaked Platinum 4 in Season 5, and Gold 1 after 16 games in Season 6 before I was perma-banned for being toxic. I've been playing Yasuo ever since season 4 and recently started to enjoy playing him more than any other champ in Season 5. I now fully main him and play him every chance I get if he is not banned or picked. I have a very high winrate and KDA and feel very comfortable playing him. Thanks for reading my guide, I hope you enjoyed reading it and I hope it helped you.
