He is really good in early and late game he is very strong if you can get feeded and you can get phantom dancer or static shiv and infinity edge.

I recommend you to build Phantom Dancer or Static Shiv after that Infinity Edge and Bloodthister and Ravenous Hydra and then maybe Mercurial Scimitar and a Elixir of Wrath-(you need level 9).

I really like playing yasuo because i think you need to have skill to play the champ not like annie or cait that they have no mechanics and a re so easy to play.I main him and i really have fun when im playing him.I don't recommend you to play him if you don't know what your doing.
