So I was messing around and I found out that on CH anti-air 5B you can follow it up with 6A, so instead of doing 5B > Aerial or 5B > 2C > 3/6D, you can do;
(Midscreen)
(CH) Anti-air 5B > 6A > 66 > 5B > TCL > 3D = 3307 + (LW)
Or if it carries them to the corner you can do;
(CH) Anti-air 5B > 6A > 66 > 5B > TCL > 5B > 2C > 5B > aerial = 4137 + (UW)
If they're low to the ground when you hit them you can omit the 5B and just go straight into TCL.
The only time when it didn't work was when I was in the corner, since the 6A wasn't causing them to wall bounce, but besides that it worked everywhere else, including the corner (but if they're too high up, the 6A brings them out of the corner). Of course if you have weak points you can do 6A > 236D > etc. or 6A > TC > 236D > etc. and likewise with meter, you can do j.D > RC > j.C > etc.
I tested it out on Ragna, Tager, Arakune, Platinum and Rachel and it works on all of them, so I'm assuming it works on most of the cast.
I've not seen anyone use this so I don't know if it's because there are better combo routes of an anti air CH 5B without meter and weakpoints, and I'm not too great at creating my own combos so I don't know how well optimized this is.
