Let's see, this was taking into account that you see Double Leader as completely and totally illegal... That was you, right?
OK then, if you see Mint as slower than the FFT mages, she casts Nurse instead, and Quick'd Lucia would be faster than the mages (since she's barely below average speed before, and getting 1.5 times that after Quick? Yeowza. Hell, by standards, she probably even beats out Tir and Riou for speed by series averages, in which case she does the Auto-Crit oil and make Tir and Riou auto-crit things, since Suikoden crits can't be countered).
EDIT: Lost my train of thought to that split-path. Anywho, yeah. Mint's on healing, Wizard has to deal with awesome MDEF for status working (which I kinda remember wasn't very high to begin with), and Lilka Quicks again. Crit oil, Tir and Riou, blah blah blah. Hell, since FFT status doesn't last after the battle, Lucia uses Crit oil off the bat. Either Tir or Riou doesn't get hit by status (thanks to awesome MDEF), and they attack. If Lilka wasn't hit as well (really bad status (in terms of incapacitating) has, what... 50% chance AT BEST of hitting average MDEF? At least, from my experience...) Then she just Restores the status away (what? L2 magic can be acquired as soon as you get the Teleport Orb at T'Bok Village, and Restore is cheap!)
It just goes down from there.
