After the standard corner BNB with B22F3, it's possible to open someone up with a mix up by using F3 as your ender. To allow for this all you have to do is incorporate the MB DB3 extension with B22F3 and go for a double F3. An example BNB would go as follows: B22F3 > LK (DF1) > D1D2 > F3 > F3 > RMS Run > F3.
From here the knockdown, although techable with a roll, still allows for a cross up due to how RMS Run interacts with the opponent. The main weakness of this set up include being susceptible to delayed wake up and putting yourself in the corner if blocked. However, in the ideal scenario you're able to score unclashable damage as replicating this set up only requires that you knock them down with F3 in the corner, so in theory you can put them in a vortex of unclashable damage.
I still need to test it versus the entire cast so if anyone here is willing to help it'd be greatly appreciated!
