Hey guys, I'm not sure if this has already been posted, but I found a really powerful combo last night in training. I skimmed the thread, but ~30 pages is a lot of stuff to dig through.
CH 6c>236cc>3d~3>3d>j.b+c (I hope I typed that out correctly). Essentially, once you launch them with 236cc, you bounce off them twice with 3d and end with the air grab. Does ~4k damage.
It also works off of standalone 236cc (which is a little risky as we know) or a 4.b+c>236cc setup but both of those do significantly less damage (around 3k).
I've tested it in training with Ragna, Jin, AND Carl (not like we need any more help with him, but hey, a universal combo is pretty nice). I've got aerial recovery set to random and playing around with the settings, it seems like if you get the timing down right, there's not a thing they can do. It's a guaranteed hit if they don't try and tech out.
Again, sorry if this is old news, just trying to help.
