Note: I didn't include drive only combos because stock builds faster than drive anyway. You'll likely be able to do the 1 stock, 1 drive combos at the same time you could do just stock combos. Also, if you remove the EX moves, it's about the same :/
Also, for you have to time j.C just right for some of the combos or the follow up might whiff. That's why I included an easier one. I.E j.C, d.b x2, qcf+AC, f+B (Sometimes will whiff if you did the j.C too late), but f+D will always work.
