After it was mentioned by
Gaiden that GA had a true vortex in the corner I tried to find out what it is. Honestly I have no idea how it works but I've been trying to figure it out. I figured it would have something to do with electric arrows because they give you stagger and you can't really follow up with anything besides b3 from mid screen because of how far they get pushed back. Also I figured the only string that could even lead to a vortex is f2d13 because it's the only one you can really get a 50/50 going off of. The problem is if you do f2d1 electric arrow you just get that small damage and go back into f2 whatever. You get 2 electric arrows so if you manage to get them with the overhead at the end before you run out you can get more damage but it's still low. Also because you need to do a string in order to get the 50/50 going it can just be push blocked.
I'm not sure what the vortex is but this is all I came up with... You can also add in shit like B13 low/jump arrow or dash cancel.
I call it the fake corner vortex. As far as I know a true vortex is something that puts you in a situation where your only option is to guess to escape. In GA's case I can't find a single situation where that's the case, mostly due to pushblock.
I'm only posting it to see if other people can try to experiment with this concept to come up with something that works well.
