Testing in training i didn't have seen this combo before :
s.C,rekka EX (4),qcb.D,s.C, rekka 444 dmg 1 ex 1 drive and travel the whole screen lol
d.B,d.B,s.B,s.B,... does 379
Very good damages for a midscreen combo, and not that hard to do.
NVM, the "classic" juggle is better,
s.C,rekka EX (5),qcb.D,qcb.B,qcb.B,s.C 458
