Adel vs. Arnaud
Adel vs. Clarissa
Adel vs. Edgar - AHAHAHAHA Adel basically. Spoils people who are all-MT and isn't winning in heavy otherwise. (Think the FF6 damage average should be lower, too, on the Edgar vote.)
Arnaud vs. Clarissa - Easy to forget Arnaud has good HP, and his bad defense is irrelephant.... though... there's an argument for the Clarissa 2HKO with sacrifice? Eh, think she needs a 3HKO meaning Reflect's chances are too good.
Arnaud vs. Edgar
Clarissa vs. Edgar - Uh, Edgar had good MBlock, right? Coinflippy match since all of Rob Turn->Sac->Sac have to hit, and FF6 MBlock is badass enough to maybe mess with Sacrifice's hit rate (though I think only Prevent can screw up its hit rate in XF). Eh, will lean Clarissa anyway.
