As a noel main, I'd say this matchup is 6/4 Valk's favor.
Noel's blockstrings are pretty predictable and her overhead is easy to react to also.
Valk should be able to out range her and fish for counterhits.
Uhh generally, I'd say noel's jA beats or trades with Valk's j.b/c but it depends on the distance and who's higher.
Try not to get caught by a surprise 3C Valk is VERY easy to haida loop.
Wolf cancels confuse the hell out of me and i never know what to do vs them. I usually jump but...yeah theres no "reversal" for that. Use them to your advantage but dont get predictable.
I see a lot of valk's using 236C (the uppercut or w.e) at the end of their blockstrings. Uh...don't do this, or do it sparingly. You'll get 5D'd.
that's all i've got for you really.
Valk's high damage makes noel afraid to take any risky moves. Expect her to be fishing for 5b/5c counter hits.
Actually noel's 5b is pretty good at counter hitting some of valk's normals since it's faster. 5b ch leads to 3c which leads to like what...3k? 2.8k? Just be aware of it i guess.
