The last 3 minutes of this video should help you figure things you can do with the strings. The s.H leaves you at plus 12 on block so you can easily dash back in and do another MFC’d s.H or string that ends in MFC’d s.H to stay in. If they tried to stick out a normal or advance guard at a bad time you can hit them for a combo. If they advance gaurd the MFC’d s.H, X-23’s wave dash is so fast and the block stun from the MFC’d s.H lasts so long that you can get in and s.H MFC them again and stay in. Creating a psuedo infinite block string.
I have a tournament match from a single elim slow tournament that I’m participating in where all the matches are played FT5. When the video gets on youtube I’ll post that up so you can see some of the corner pressure I used with it in the match also.
