Just about any bruiser or juggernaut goes well into yasuo
JuggerNauts who shit on yasuo
-Has a passive that allows him to win every long term set of trading, and a q that will heal him in mid fight, once he has his R he becomes very hard to out play because he can now kill you the moment you enter 50 percent health range
-Easier to deal with than let's say Darius, but has a ultimate that allows him to completely reset the fight, very hard to deal with if you do not yet have your bork or mortal reminder, for he simply negates all your damage
-While no where near as hard as darius, Yasuo has to be careful with him, for once again once you are in the 40/50 percent health range, you are dead
-Yasuo likes to get up close and personal, and so does riven, she has 2 different ways to cc you to stop your combos, a shield to block your combo, and yet another execution ultimate, that guarentees your death, however you are given more breathing room with riven, for you have the ability to out play her, unlike with the first champion mentioned
-If he times his E perfectly, than you have no hope to beat him in a one v one, as his Blocks your autos and your Q which is roughly 70 percent of your damage.
