This one is extreme if you never pulled on latest banners. At first, I tried for Bartz over Lenna but can't breach the 350k score. I'll try it again at a later time.
Strat for the run
First wave: Use Firion seize attack for buffs, Lenna's rapidfire for mbrv and 2 times multihit on OK
2nd wave: Kill the Iguions simultaneously, no other options. Try to save Firion's weaponmaster and OK's blizzard when killing them.
3rd wave: Kill for overkills.
4th wave: Nothing special, just beware of turn order or they might kill you after an all attack.
5th wave: Immediately swap OK to Quistis, use degenerator once, summon, and be sure to have Firion's Ex ready. Try to overflow with blood weapon when nearing max brv.
Lastly, hope for good RNG for this run.
