Ladies men:
Edgar (FF6), Zelos (ToS), Ronfar (Lunar 2) vs. Necrosaro (DW4), Hect (G3), Eileen (S1)
Uh, this enemy team is insanely bad. Necrosaro could theoretically outlast teams with 0 healing but his first form is insanely bad and enemy teams will always leave him for last. Hect is slow & frail and Armageddon is slower. So yeah, Eileen is the only character who can carry here, but I assume Copper Flesh doesn't do anything against status. Anyway, if Eileen goes for damage, everyone murders Hect and Ronfar heals. If Eileen makes Hect invincible, confuse Eileen... (I'm not going to hype Necrosaro as smart enough to attack her)... Hect gets 1 turn, and if she attacks Eileen, then the team never makes any progress. If she does something herself, I don't think she has anything decisive enough to deal with Eileen turning traitor the next round and Earthquaking the team or something. Ronfar keeps the team healed up after Hect & Eileen are dead and they start mowing through Necrosaro forms.
Edgar (FF6), Zelos (ToS), Ronfar (Lunar 2) vs. Kornell (G3), Lundgen (FE7), Fogel (OB)
This team is very mono-physical, but also very boss-heavy (even if hyping immunity for OB/FE bosses is a bit chancy), which kind of turns off Edgar. Also I let Kornell have the Iron Fist actions so he's pretty badass and the team can surely take down Ronfar first before he gets an action.
Edgar (FF6), Zelos (ToS), Ronfar (Lunar 2) vs. Loki (VP), Georg (Suikos)
Loki reks with MT physicals, Georg cleans up any survivors. Suiko5 arguably resitss some of Edgar's nonsense anyway - probably not Air Anchor but dealing with Georg is the least of the problems here.
Edgar (FF6), Zelos (ToS), Ronfar (Lunar 2) vs. Beatrix (FF9), Fenril (OB), Tifa (FF7), Reis (FFT)
super behind the enemy team selection with all the OB hype. Anyway I never know what to make of Beatrix scaling, but boss form isn't bad, especially if you're willing to hype the plot-esque HP-1 final attack upon defeat. I think rushing down Ronfar should work though; Zelos healing possibly isn't even relevant, but even if it is, I don't think Edgar does enough damage before things come tumbling down anyway.
Someone gag them already:
Decus (SO2), Precis (SO2), Chu-chu (XG) vs. Necrosaro (DW4), Hect (G3), Eileen (S1)
This team doesn't really have status, so Copper Flesh spam actually works. And Forest Dance is actually ST. Fail. If it was MT this might actually work. As is, Eileen can go invincible than reliably spam out her 4 EQs... except... Decus nulls (nearly) all elements? Well that's random, I guess Decus solos then or something. BUT NECROSARO IMMUNES FIRE. WTF. Okay, Eileen goes invincible, Hect stat-busts Decus, Hect dies to 2x Precis turns, Eileen EQ spam wipes out Precis and forces Chu-Chu to spam healing on herself and possibly eventually kills her anyway but is then worthless vs. Decus, then stat-busted Decus & Necrosaro have a slap-fight with 10HKO physicals. Except Necrosaro eventually evolves to have non-sucky damage. Sheesh. I guess if you see Chu-Chu as more durable / Eileen's damage as worse, Chu-Chu might survive and somehow contribute to Decus, but eh.
Decus (SO2), Precis (SO2), Chu-chu (XG) vs. Kornell (G3), Lundgen (FE7), Fogel (OB)
Decus (SO2), Precis (SO2), Chu-chu (XG) vs. Loki (VP), Georg (Suikos)
Decus (SO2), Precis (SO2), Chu-chu (XG) vs. Beatrix (FF9), Fenril (OB), Tifa (FF7), Reis (FFT)
These three are not close. Decus isn't soloing.
I wanna be the next Dr. Wily
Hojo (FF7), Bowman (SO2), Lexis (Lufia 2) vs. Necrosaro (DW4), Hect (G3), Eileen (S1)
The only way this team does anything is if Lexis gets chipped into some incredible IP, which is hard in a team-fight since I'd enforce it coming out on turn 2 at hte earliest. Hojo1 is trash, Bowman is nothing special.
Hojo (FF7), Bowman (SO2), Lexis (Lufia 2) vs. Kornell (G3), Lundgen (FE7), Fogel (OB)
Hojo (FF7), Bowman (SO2), Lexis (Lufia 2) vs. Loki (VP), Georg (Suikos)
Hojo (FF7), Bowman (SO2), Lexis (Lufia 2) vs. Beatrix (FF9), Fenril (OB), Tifa (FF7), Reis (FFT)
And the team loses even harder here.
