Yeah, I realised that while putting together my own votes. It is indeed.
Pool C
The Eternal Bard (FFT) vs. White Mage Khimari: There's nothing that stops him from getting an Overdrive that I can see.
Speedy Teepo vs. Laggy's Gen 3 Jumpluff: Not to be a jerk, but uh seriously, who nommed twinked Teepo? We don't even have regular Teepo stats, and he can't possibly meet Meryleep in-game. WTF? He probably matches up well against Jumpluff since he has Frost, which should be near OHKO to average (EDIT: against Jumpluff's W4 to ice, to be clear)... but of course if Jumpluff is faster, then Sleep Powder / Sub / Leech Seed probably does its things, since I don't think Teepo can block sleep. This might merit more analysis, but yeah, I'm voting for the one who is a legal build.
Lightning Mel and Thunder God Branky vs. Statmaster Silence: Equip Rubber Shoes, MagicHeal off Mel's attempts at offence.
Officer Mariel (WA:ACF) vs. Burlesque Dancer (FFT): Not sure how to take Mariel, so copying the crowd.
Pool D
White Mage Aeris vs. Pearl Magi Relm: Relm is going to block Slow because duh. The big problem is Seal Evil and its Stop, yeah, which Relm can't block and lasts quite a while. Aeris just needs to heal after any Relm attack and she's guaranteed to see a limit. Aeris has... 378 MP (don't forget about the +14% from her matiera!), so unless Relm attacks (in which case she heals and is closer to a limit), she uses Haste, and Dispel costs more of Relm's resources. Aeris' base physical is probably somewhat better than Relm's, too, so I have to think she'll win the resource war.
Furious Vincent vs. Crested Lemina: Lemina has a 3HKO here, and can't avoid a limit, which she needs two shots to trigger, then 3 more to kill. At least she has the MP for that! She also has an eternal 3-2, so the turn order as far as I'm concerned goes Lemina, Vincent, Lemina, (Vincent ATB fills due to limit, gets an attack), Lemina, Vincent, Lemina x2. So can she survive three Vincent attacks? It's close... except Lemina has the regen, so she wins. He may take this if you have less respect for high TB speed than me, depends on how you feel about 30% status.
MegaMari... belle vs. Frog Pope Malak: After adjusting for faith, Maribelle does 78 damage with Celica's Gale (46 normally, saving that for later). Malak has 84% HP as a Wizard... which means he barely, barely isn't OHKOed unless you factor in accuracy. If you do, you presumably do that for Celica's Gale as well... and it still just misses the OHKO using 83 hit (=94.2 real). Someone may want to check my calculations here since it is close. So... only question left is if Frog is turn 1? ... oh hell no, that Res is really good, halving damage (and if Faith halves damage in FFT, it also halves status hit rates). Maribelle obviously finishes the 2HKO next turn. Malak is spoiled.
