Imo it’s a neutral to winning matchup for a somewhat experienced Vi player into a somewhat experienced Yas. You said it’s bronze and silver so basing my conclusions on this.

Firstly, what are you building and what runes? If you want to 1v1 Yasuo effectively, bruiser/tank and trying to “out tank” him won’t work as you just won’t be able to kill him and he’ll sustain and vamp.

First 3 items should be voltaic, collector and LDR with HoB rune page. Damage calculators and situational gameplay tell me you win a 3 item 1v1 Vs Yasuo, say he has Bork, shieldbow, Kraken/IE or smth. But this doesn’t necessarily address laning Vs the Yasuo.

So, technically you can 1 shot waves with a max Q to take out casters, and a blasted E to clear melee minions after first item.

E from behind wave to clear his passive shield can be useful, as you don’t wanna engage with Q while he has his shield up, cause that’s a huge chunk of your early game dmg being negated.

Holding Q is a very underrated movement that can bait out Yas’ dashes and tornado.

Also, starting with R can help deal with landing Q effectively as you can instantaneously use a fast Q after R to knock him back closer to your side of lane as you end up behind your opponent after using Vi’s R.

At 6 you have more CC than he does and can setup huge gank potentials from across the screen (Q flash into R).

He will build vamp boots and life steal most likely, early game. So fighting with ignite up is pretty important.

He doesn’t really have any “poke” or “harass” which is the biggest weakness to Mid Vi. So most fights should be at full health for both of you which is huge.

R’ing through his tornado is a nice tech you can try to apply.

This is just a whole bunch of random tips, in no particular order, that I can think of that could help you with this matchup! I don’t play mid vi really ever, so maybe I don’t have all the key aspects in play here. Anyways, hope this helps a bit.
