From my match experience 3C just clashes.
I tested it in training mode just now, and 2B > 3C just clashes with DP > DP. I can just do an unlimited amount of clashes between 3C and her DP. I could be doing it wrong though, but it is pretty much what I expected.
Maybe she can 6B out and over anyway.
5A would be too far for Hakumen to punish with. And using 2B just ends in more clashes. clashmaster 2 strong
Just tested her 6B. 6B gets beat by 3C out of DP but not by 2B, 2B whiffs and you get hit.
So it basically after the first 2B clashes it boils down to a guessing game: if she DPs again, it will beat / clash with everything, but you can punish by just not doing anything after 2B and letting her next DP whiff. If she does something other than DP, like 5C, it will get eaten by a 3C but get her out if you were baiting DP.
Oh wait, but her 2B beats your 3C too. I need to make a graph out of this. :V
In any case clashing with her is a bad time. I'd rather just make the DP whiff so she can't RC or do any stupid bullshit off it.
