Okay, I think I'm going to go ahead and trade out Yulie (2.0) for Tear (1.0) and Aeris (1.0).
Getting an extra warm body in the mix is always a pretty decent idea, and this gives me more healers. I also get some more direct offense with Tear's offensive spells (and if necessary, she has some passable physical chains). Also, a OPF shot of her Overlimit which she would have probably never seen anyway. Innocent Shine by itself isn't too special, but she can combo it from one of her strongest spells or FOF-cancel into it for one shot of decent OHKO damage. Not until Floor 3/4, though, when the Mystic Artes become available. Before that, she can blow her Overlimit meter on faster casting times/increased damage for healing and offensive magic. If she makes it to the floor where she gets her Pendant, she's actually a pretty respectable Healer-Mage. If only she was something besides average speed (or less, depending on your interp).
Aeris isn't bringing much, but I guess she doesn't need to do much besides healing. She's faster than Tear at that, at least. Also, OPF Great Gospel eventually! This might even be Floor 2? Before that, Seal Evil is pretty decent, even OPF. Too bad she can't use her 'give up Limit meter to fill the rest of the party's Limit meters' ability with VBL. That would have made for AMAZING Aika synergy here. The wording is VBL is too strict though. If it was 'Limit meters do not fill by normal means (aka damage, defending)', then I would see a move that specifically restores Limit meters as working. But it says 'Limit meters can not be restored by any means'. Oh well. Anyway, Aeris' Restore materia lets Cloud concentrate on other things earlier in the Dungeon. Like Revive and Cover... >.>;; Cover's going to be so much more important now that I have more warm bodies with little to no durability...
Dropping Yulie also means I don't waste any of Raquel's precious FP, but I lose her awesome buffs (Tear's are good, but she gets them much later... less resources early on, too). And the dual tech MP-restore with Raquel is gone, too. Hopefully Cloud/Aika's MP reserves hold out...
So, the new Team Djinn (aka Team We Abuse Limits!)
Cloud (4.0)
Raquel (3.0)
Aika (2.0)
Tear (1.0)
Aeris (1.0)
(Violent Burst Law Sealstone)
I think as long as Aika saves enough SP for the Rampage Drive fight to waste him with Alpha Burst, this team should at least survive to Floor 3! Whee~
