Way of the Wanderer
Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Split Pushing Monster
If you're really confident with your Yasuo play AND you know that your team can apply pressure elsewhere in the map, try this build. It min-maxes dueling potential when alone.
Team Player Tanksuo
If you expect to be teamfighting a lot and want to set your team up for some serious wombo, this is the build for you.
