With his meteor Jellal could easily snatch the staffes away from Mystogan, leaving the latter next to helpless.

Even without such underhanded tactics I doubt the "mere" S-Class mage Mystogan would have much of a chance against the Ten Wizard Saints Jellal.

I guess it is possible that we never saw Mystogans best attacks in the few fighting scenes he had, but with what we have seen he wouldn't even put a scratch on a full-powered Jellal, no matter if pre or post timeskip.
