Here comes the sun (No Mega forms):
Ho-oh, Groudon, Exeggutor (Pokemon) vs. Lambda (WA4), Antenora, Tony Eisler: Status is out, but the pokemon come out swinging hard, and Lambda can't keep any of them from getting turns. Ho-oh + Groudon EQ probably kills Antenora. The real problem is Lambda whose damage can just add up over time... Exeggutor can use Reflect so that Ho-oh doesn't need to fear him, though, and they can kill Tony on turn 2 at worst. Think the mons have this.
Ho-oh, Groudon, Exeggutor (Pokemon) vs. Rutee (ToD), Alfina (G3), Evans (BoF): The pokemon unleash MT pain and I doubt either PC gets a turn. That leaves Evans! Wishes Coldbreath were actually ice, but what can you do. So... yeah his only hope is to try his luck with 40% ST death, that' snot working.
Ho-oh, Groudon, Exeggutor (Pokemon) vs. Xorn, Freya (FF9): Oh god, Xorn. Freya's annoying due to nulling fire and halving earth, but... hey, she can still be put to sleep (and failing that, does probably still die to halved Earthquake + Solar Beam). So... Xorn needs to solo this. Can he? Hm. He can 3HKO Ho-oh at base, so he starts out by doing that. Granted... Ho-oh can just use Recover to try to live longer, that will buy Exeggutor time to use Reflect. And... yeah Xorn can dispel that, but still. I just think the pokemon can mount a nasty offence which takes away too much of his health at once, and he's a bit too ST/physical to punish them for it.
Ho-oh, Groudon, Exeggutor (Pokemon) vs. Rupert, Jeremy, Yulie, Emma (ACF): Jeremy can wreck Exeggutor immediately, probably the move to make. (He can't get Groudon) The other two pokemon can use Earthqauke + Fire Blast to kill Yulie, and they'd damn well better. (This has the side benefit of also OHKOing Emma and Jeremy!) So... it's just Rupert, and now he's damaged, so Maximum Risk is going to wreck. Also Crisix Reflex Up. Yikes, he's 210% speed now, which probably means he starts doubleturning. Yeah, even with some misses he should take this. And there's no good way to avoid damaging Rupert like this, and the pokemon can't really focus on him either.
My Right Hand is the God (piece) Hand:
Riou, Geddoe, Lazlo vs. Lambda (WA4), Antenora, Tony Eisler: Lambda gets two turns but can't kill anyone, and any damage he does will be healed. Thunder Storm + Everlasting Mercy + Forgiver Sign means dead... Tony, we'll say, and severely damaged everyone else, and full HP team to try again. Antenora can try to status someone but Geddoe's immune to some stuff and I just don't think this is working.
Riou, Geddoe, Lazlo vs. Rutee (ToD), Alfina (G3), Evans (BoF): Again, too much magic damage too fast.
Riou, Geddoe, Lazlo vs. Xorn, Freya (FF9): Freya can null thunder and Luna is terrifying, but she can't block holy so Riou has to nuke her. This is bad because it's a shot they don't have for later. I suppose they could try to drop her with physicals, but that would probably need all three of them... or Lazlo could use Everlasting Mercy. So Xorn beats up Lazlo to make the team choose between Lazlo dying fast or saving Forgiver Sign. Without FS the team feels in really bad shape later, Geddoe damage is good but Xorn is a magic tank so we'll see a bunch of nasty Death Knells and Dimension Gates. So sure, let Lazlo die. I... still think the team gets overwhelmed, but could be argued.
Riou, Geddoe, Lazlo vs. Rupert, Jeremy, Yulie, Emma (ACF): Well Riou isn't getting a turn, Geddoe + Lazlo can kill Yulie/Emma/Jeremy but again this involves hurting Rupert and giving him tons of time, and Lazlo has no good damage left to finish Rupert after he explodes Geddoe, evade or not.
Princess Tea Party:
Princess Toadstool, Nina2, Clarissa vs. Lambda (WA4), Antenora, Tony Eisler: Am I missing something here? Lambda is 265% speed, Clarissa is 126%, he goes twice first and 2HKOs her unexceptional evade. Toadstool can revive her, but that doesn't stop the same thing from happening again, and meanwhile Tony and Antenora get turns this time too. The only tiny chance the team has is if Nina can one-shot Lambda but that's not likely.
Princess Toadstool, Nina2, Clarissa vs. Rutee (ToD), Alfina (G3), Evans (BoF): Sacrifice offs Alfina, Nina can death Rutee. Rutee gets a turn first, sure, and revives Alfina since nothing else is useful, but Toadstool + Clarissa can kill her again. As usual, all Evans can do is try for ID... on Toadstool of course because anyone else is revived, but in the meantime he gets torn apart by repeated Sacrifice + heal combos.
Princess Toadstool, Nina2, Clarissa vs. Xorn, Freya (FF9): lolno. Xorn weakens Sacrifice so that isn't a OHKO. Toadstool can put Freya to sleep (or Luna) but this means she isn't healing or reviving, I guess Nina uses Death, but then Xorn uses all these extra turns to make sure Toadstool dies and the other two aren't taking him down.
Princess Toadstool, Nina2, Clarissa vs. Rupert, Jeremy, Yulie, Emma (ACF): Jeremy kills Clarissa, then the team can't stop Yulie from getting a turn I don't think. Maaybe with two status moves, but they can't not kill Jeremy. So, uh, kill Jeremy/Emma with BoltX and revive Clarissa maybe... but then Yulie hastes Rupert and NOBODY LEAVES, AND NOBODY LIVES. Or just revives Jeremy.
