From what ive heard and played
- hold a button a to make azhi closer to waldstein and zone him with 236a > 623a (not a lot of psople will know how to punish that blockstring, cuz azhi can recover really quickly)
- If you they try to dash into you use 6c to stop it, but use it at your own risk, cuz its really punishable.
(Btw you can cancel whiff 6c into any super)
- once you get a knockdown go for oki/meatie mix-up. Because some waldstein will try to mash 360 Just like in the video he just posted.
- try to hit his claw when his whiffing some moves (like he said, sword characters can be hit on the sword while active)
Other than that... footsies/experience/fundementals. Practice the match up with someone and you should be good.
