To be honnest Zed is an easy no match for yi, he trishot him late game and can follow him back on his ult shadow with Q, even if he took a lot of damages he can still meditate to cancel most zed's ult damages.
Just meditate while kayle ult.
Riven can be annoying if she can pull a perfect combo. Trynda as well, but yi can run away with ult, and trynda can't slow him down so, he can run, and then come back when tryndas ult ends.
Vayne, well, it's vayne, depends if the condemn is good.
No way vi would win, i dont see yasuo winning either if yi is a bit tanky
It all relies on yi's itemisation and execution. Mind games to Q a condemn, a shuriken, a tornado, the riven ult on time, using the qss right, smart use of meditate to either reset auto or mitigate damages.
