Blue (Speed?) - 4.0
Toadstool - 3.0
Arnaud - 2.0
FFT Monk - 1.5
Rand - 0.5
The idea for Blue is Realm (Forced) -> Arcane -> Light -> (Floor 4) -> (Floor 5) -> Time -> Else.
The general idea is that Blue is getting the drop on EVERYTHING on turn 1, thanks to Speed? being on him (which he'll eventually give to Rand once he gets Overdrive - to which point, I'll need nothing else). Start of turn ID? There. Defensive buffing? Sure. Revival? He can pick it up in a pinch on floor 3 - I do also want Tower to be available early, for WTF damage IF and only IF I really need it.
Toadstool is healing extraordinaire. At floor 2, (that is when Rose Town is, right?) Wake Up Pins will be available, making her immune to Sleep and Silence. Later on (Floor... 4ish?), I'll be able to trade that in for elemental damage halving. It's a nice package to have, overall.
Arnaud is there for his incredible (if ST) buff and debuffs. Sure, the magic damage is nice and all, but it's something to consider if a target's speed is on par with Blue.
FFT Monk serves four functions: Earlygame physical damage. Somewhat respectable revival (it hits 3 out of 4 times right out of the gate, I wanna say?). MP healing (I'd rather ignore the HP-healing part of that, since it's so bad). Decent status healing that can't be silenced. To bolster this, he also gets Hamedo at some point, as well as Limit Range full healing. All he has for status defense are clothes and an accessory, but them's the brakes. Still useful, though.
Rand is my secondary healer/reviver/physicaler. If he's not healing, he's putting the pain on something with his fists. He has magic damage, but it looks generally unimpressive to me. It's still there, though.
Assumed floor 1 path:
Palmer and Mist Dragon - Blue's casting PsychoArmor, Toadstool is defending, Monk doesn't need to worry about Toadstool at all, so beat on Palmer some, and once he's down, beat on Mist Dragon until it Mists up. Monk takes the turns of "don't attack me, stupid" to restore everyone else's MP. Next.
Steelix, Shuckle and FF1 Knight - Blue IDs FF1 Knight, and the other two fail so much on damage and speed for words. No resource problems at all yet.
Marle, Alice and FFT Priest - Okay, this... Might get tricky. Blue and his massive speed IDs Marle (thanks Implosion!), Arnaud Slows Alice down, while Monk, Toadstool, and Rand beat up FFT Priest. Team takes an Advent to the face (or face having whoever she revives... Be completely useless, as the revived will be Slow Downed and killed off again in short order)... Toadstool heals, and the fight kinda ends there.
Rampage Drive - Rampage Drive against mostly mages. Yeah.
Lich (FF1) - Don't think Lich can stand up to the combined offense here.
Other points of interest:
FFT fights on the Floor 3 MT? Meet Tower. If that wasn't enough the first time, meet it again. And again. I've got time to spare. Arguments opposed? Monk's Chakra and other limitess amounts of healing at this point. Thank you, have a nice evening, floor 3.
