Vladimir

Top or mid? If top, go for it, but expect a lot of harass coming your way.

If mid, then no, he will be able to wreck you with any gank.

ALSO, I'm not sure if wind wall blocks your E. If it does, then absolutely do not take Vlad.

If you don't know how to play Vlad to begin with don't pick him. Pick a champion you are actually good at and know.

if you do know him, unless you know a champion is a 100% hard counter pick him anyway.

The match up is skill based between and . Vlad's E will be blocked by the windwall. The Q will not. Yasuo is very mobile and that "can" spell doom for Vlad. But, Vlad has some good escapes. My suggestion is if you do this match up, poke, poke, poke, and start with the Doran's Shield. Get WotA and SV right away

Yasuo really hates a good vlad player. Early vlad has to watch where he steps. Poke yas and just farm after his first back yasuo can throw out his wall vlad can q him after it falls e and q farm with autos and e and just push yas out of lane. Can dodge the knockup or make some sick outplays by having a little more hp then yas with wota and yas isnt fed vlad lets yas knock him up you have 4 e stacks and e<q<r<w<ignite while running away and if he runs flash e<q for kill. I like Vlad more as yas is not as good in this meta even though I really like yas's kit, imo kinda useless when doing fine and completely useless when behind and not super impressive when fed.
