Doing some experimentation against Algol's bubbles, I noticed that using A+B to auti-gi them back instead of a regular GI recovers far far far slower, as opposed to a regular GI where you can move more or less immediately.
Against his 6BB B bubble, if you A+B auto-gi it, you can't recover fast enough to actually do anything with the bubble up close. If you 4A+B+K it, you can run forwards on top of the bubble and apply some reverse pressure of your own. The A+B auto-gi also starts too late to auto-gi 6BB B on hit, while 4A+B+K is. If the spacing is far enough, if you 4A+B+K the bubble and 4B immediately, if the bubble hits, the 4B will combo for huge damage potential (bubble 4B 66B BE 22BAK is 122), or 236B:4 will do so closer up for 82 damage (its like being Viola for a split second yay!).
There's also time even on hit to CE after being hit by 6BB and auto-gi or go through the bubble. Though on hit, he can block the CE as you're delay by 6BB's on hit frames, on block you can nail him regardless of bubble.
Against his 2B+K B bubble, if you block 2B+K, you don't have time to A+B, but, 4A+B+K will immediately hit him and counter hit him even. Though there was a weird recovery time for Pyrrha, so I couldn't combo anything off of it, which makes this kind of pointless as you can meterless 236B:4 punish it for more anyways. If you have absolutely perfect timing, you can CE after 2B+K and it will auto-gi the bubble way off axis to the side, which is convenient as it block punishes 2B+K anyways.
If you 4A+B+K GI his 8B+K B aerial bubble, you can 22BAK combo him before he lands.
Also A+B is buggy, in that if he launches a second bubble, it will try to auto-gi that one and not the bubble closest to you (so doesn't work against 8B+K BBBB). 4A+B+K doesnt have this problem.
