I use Selphie every once in a while. Her Full-Cure comes up quite often, and it's always very helpful. Not to mention that she does have some pretty awesome spells in her Slots. Rapture is like a Degenerator on all enemies, and it comes up fairly regularly. Once I got Meteor x 27, and BGH251F2 went down like a rock in a pond. Not to mention that he has a decent strength stat, and her weapons have pretty good Hit%.
