Bartz is dying or being locked to resurrection ASAP and his status is mostly if not entirely ST. If Peppita goes for purely status I'm not sure she'd be at all useful against the multiple bosses on the floor, and Aeris is limit. Really, the only person available for status is Peppita, and she has to either choose status wisely or be limited to pretty much status only.
For example, fight 2: Yuna/Flik/Georg kill Bartz before he blinks, Fogel can only eliminate one. Peppita can status one of the three (though if S5 has Yellow Scarfs Georg shakes his head) but she's average speed and can't stop the rush.
If DL Legal Rikku means "common items" the entire team falls there, as a side note; Fogel kills Rikku but Yuna revives and Flik/Georg kill people during the warring over Rikku. If Rikku's ever left to get a turn, bam, statues.
And the next fight, even presuming only Bartz falls fight 2, has five people, four of whom are dangerous (Zeakden Algus scaled might be kinda semi frustrating to kill, but that's giving him a lot of credit). This being said, Wiegraf gives some fits, Velius needs to die fast or Fogel gets eliminated to status (and I don't buy a Fogel OHKO, though it's close), Pikachu can just toss a Paralyze at Aeris or Thunder someone... yeah. I have issues seeing them pass the first three fights, especially since I didn't factor the first fight in at all, in which Lucia/Valvalis may be enough to disable or kill Bartz, creating major issues fight 2 where the non-Fogels get picked off and weaken him for the final fight. Yeah, definite fail to Uno's team, looking at it. Really needed another reviver by this point.
