He doesnt do much without meter... s.D, dp+C/hcb+D is your best punish... In the corner he can do s.D, qcf+A, dp+C... Ideally you wanna have meter with him... Cause s.D, f+A, DM/EX-DM does a lot for a punish...
Also try to land counter hit j.C+Ds... It nets you free damage anywhere... Hcb+D afterwards and try to corner them... In the corner this gets stupid... You can land j.C+D, qcf+A, hcb+D, dp+C, DC, hcb+D, dp+C/A depending on their height... It only costs one drive, builds you a shit load of meter and does over 500 dmg...
LMFAO... Do this from starting position... Super jump CH j.C+D, qcf+A x5!!!!!!!!!!, qcf+A, (dp+C, DC, hcb+D) x2, dp+AC... WOW...!!!
