So my english is not on the highest lvl but ill try to explain this build.It grands Yasuo sustain on lane thanks to botrk tank shredding possibility and high suvability,i found this build when i was trying in normal game and it went so well so i tried it in ranked and it work the only match-up i found that is very hard is renekton but thats normal he can one shot yasuo on lvl 3 darius,garen and jax are skill match-ups that arent that hard when you fint that right counter play for darius is to kite him but dodge Q for garen is to kite and slide away when he is E and fore jax is to dodge E. I found this build very useful in gold and plat.
