OK, I... Uh...

OK, if everyone's faster than the opposing team after Quick (which would make sense for at least Lucia and Mint, since under their system, they CAN take advantage of it right away), Lilka does so, Tir and Riou tink away at Zalbag, Lucia uses Moon + Night to give Tir and Riou auto-crits (which are TRIPLE NORMAL PHYSICAL DAMAGE if I remember correctly), and Mint uses Haste. Overall effect: my team is now given ~250% more speed than usual (depending on interpretation; if you see Haste as doing nothing, then Mint instead uses Acid Rain).
Other team goes. Alma casts MBarrier. Ramza uses Scream. Zalbag uses Speed Ruin. Net effect: FFT team is MBarrier'd, has one Scream in use, and my team is now back to about average speed.
My turn again (somewhat): Lilka uses Dispel. MBarrier goes bye-bye. Tir and Riou crit against Zalbag. Zalbag goes bye-bye (thanks to auto-crits from Lucia and lowered defense from Mint's Acid Rain). Next is probably Alma using MBarrier again followed by another Ramza Scream. Lucia switches gears to using Gale. Mint either uses Charge (to give Lucia more MP) or Delay (to slow down Team FFT, if you see it working).
Next round: Lilka uses Dispel again (even after Hasting, Alma and Ramza aren't fast enough to lap Lilka right then and there, especially after Gale), Tir and Riou either tink defend. Alma casts MBarrier again, Ramza uses Scream again... OK, now it's getting dangerous. Lucia uses Night + Moon again in anticipation, Mint uses Deep Mist to lower enemy accuracy. Now, uh... Crap, I'm getting lost in my numbers.
Now, uh... Lilka's using Dispel again, and Tir/Riou go after Ramza this time (killing him), and then it's just a matter of surviving an Alma Ultima to win, right?
Bah... I was getting so excited for when I'd finally get in, and I screw up like this...
EDIT: Actually... As far as I know, my speed would be HIGHER after a Zalbag Speed Ruin, since the value for the RFX (speed) increase has already been added by the time he gets his turn... At least, I think so.
