If you jG the 1st hit of Asta BE Bullrush you can squeeze in a thrust for like 60 damage. If you block the first hit of his BE Bullshit you can squeeze a CE in there. You can 4A but Raph still gets hit even though he'll be off to the side because Namco sucks at hit boxes. If you block both 1AA you can do a thrust before he can stand up unless at range 2048204589 or some shit. If you block 1A you can 8B the 2nd , doing that on 1AB will get you killed. IIRC you can block the 1st of 1AB and thrust before he can get the B of 1AB out. If you jG the first hit you can squeeze a 66B+K over the 2nd A of 1AA. You have plenty of time to stand up and B+K the B of 1AB, or 4A it. If Asta tries 44[A] you can 4A+B it pretty easily and the timing come to find out it very generous. Just wait until you see his axe catch on lightning and then 4A+B. You don't have to do much more to time it then that, the attack seems to connect dead in the center of Raph's aGI frames meaning that you can be quite early with it and still get the aGI, it is important to note that if you wait until the circle of spark closes you're screwed and will have to block because Raph 4A+B takes days to come out. But basically any time the lightning is on is good to go. Also don't forget 4A+BB will wall splat so have a combo ready or some shit. I forgot to test shit for Asta 66AB and some other crap but whatever, my wife got home from work before I could do more.
