Godlike:
Weisheit (XF) vs Asellus (SaGa): The strategy Super puts forward is amusing, but I don't think Asellus has the JP to make it work. I probably see her very poor in the stat indeed since training in magic hurts physical stats a fair deal relatively, and she won't want to do that for the vast majority of fights where her only use for magic is tossing out a Fascination. Even if I give her a lot, though... she needs to cast it so many times, it costs 5 JP... just doubt it's going to work unless you see her 2HKOing Weis or something like that. I definitely don't.
Millenia (G2) vs Rubicant (FF4): Yup.
Heavy:
1-Wren (PS4) vs Lyon (S5): Barrier and death immunity are bad news (definitely don't see Setting Sun as the mech-killing type).
Lilka Eleniak (WA2) vs Lucian (VP1): Yeah, her evade buff isn't good enough for turn 1.
Sharon (LoL2) vs Alex (Lunar:SSSC): Turn 2 charm if she doesn't just 2-round.
Queen Zeal (CT) vs 3-Shadow (FF6): Shadow is probably 2HKOed by Hexagon Mist or something embarrassing. At worst, though, 3HKOed and he doesn't even come close to outslugging that. He could take a crazy GRAVITY ROD stall strategy but it makes his speed and durability even worse (2HKO feels near certain now) so no.
Middle:
1-Rudy Roughknight (WA1) vs Warlock (S4): Think he tanks an EQ. Might just OHKO anyway, Warlock HP was pretty bad and I don't have the same respect for Jack's/Ceci's damage as the stat topic due to no runes.
Flare (S4) vs L'Arachel (FE8): Don't think Flare has enough shots of healing to double twice. Flare fans, I know you're out there, convince me I'm wrong, I'm lazy.
Lucia (Lunar:EBC) vs Jessica Philomele (MK): She had some timed card stuff, right? (besides healing) Something that would overpower Lucia? Break damage I probably see working eventually, at worst.
Rouge (Saga) vs 4-Tengaar (Suikos): ... riiight, Jet Boots were storebought. Somehow I never knew until now that Saga walled earth. -10 speed to get it, though. Tengaar has some crazy argument involving the now stupidly slow Rouge, spamming Vengeful Child to earn doubles, and hitting his now pathetic durability 3 times or so to win. That's... um... actually surprisingly reasonable, especially if Implosion isn't turn 1 (I'm really not sure, felt kinda borderline 1-2...). I dunno!
Light:
1- Zappa (CC) vs Louise (FE7): Surely. Zappa is decentish.
Rody (S3) vs Cyan Garamonde (FF6): It's Rody.
