Indalecio vs Sofia: Close, but I don't think Sofia QUITE 2HKOs through ToT, nor is she faster, so Indalecio has time to dispel then OHKO with Earthquake.
Indaleico vs Cecilia: Parasol. Seems pretty open and shut from there.
Indalecio vs Rubicant: 2HKOs. Granted, Indalecio might 2HKO first, but he both needs to be faster and have that 2HKO. Could make either call either way, so going with the 75% chance here.
Indalecio vs Seymour: Seymour's not weak to Water. That said his MDur isn't really cutting it here anyway. At best he 2HKOs, and faces Star Flare + Southern Cross. He probably can't handle that. Though... actually, maybe he can? I dunno. Of course he might fail to 2HKO, so sure, let's play that 75% chance again.
Altima vs Sofia: Non-magical status death.
Altima vs Cecilia: Hmm yeah, form 1 does need more speed. Lock State. That said, Mute hits through all of Cecilia's tricks, which reaaaally puts her on the defensive. And then Dispel + Grand Cross ensues. Don't think she can manage; she'd pretty much need to blitz, and I can't see that working out well. Quick, Dualcast Holy spells... adds up, but I don't think it's good enough. May change if the Holy summon is better than I think.
