I would suggest testing that combo versus air control. You can do this by going into 2p settings and setting different directions. I can garauntee just by looking at the length of that combo that it's invalidated after the 2nd 4b+k. probably the first depending upon exactly what 4b+k does versus air control. (never tried it!). As a rule, very few moves prohibit air control, and generic AAs definitely don't. The only Aeon move i'm aware of that prohibits air control is BT B+K.
Don't stop searching though! You never know what you'll find, but in high levels, everyone air controls.
yeah, I noticed that ingame you can't air controle with AA, I did this combo in training, I'm new to soul calibur so: what's up with that? And by the way, what does BT B+K mean, the BT part that is??
