close C qcf+A > f+D should work if you cancel the first hit of close C.
close C, f+A, activate, close C qcf+A > f+D, qcb+D > qcb+D, [dp+A (1 hit) qcb+B/D > qcb+B/D] x3 dp+A (1hit) qcf+C > f+D, f+A, super xx Neo max
^that should still work.
It doesn't work anymore in console. The best you can get is C (1hit), qcf+A, f+D
For HD combos do j.D, C(1hit), f+A, BC, C(1hit), f+A, [dp+A(1hit), qcb+D, qcb+D(miss)] x 4 or 5 I forgot, then dp+A(1hit), qcf+C, f+D, f+A, finisher
Finisher can be dp+C or qcf, hcb+P
