Just cleared it once with maxed OE Lance and mostly maxed Finkell (BB 10, max level, and dual spheres, but very few imps.) Lance's UBB was extremely useful. Finkell was actually the main cleanser and healer though, since I didn't have BB management on Lance at the time. I used Sacred Light as back-up and did have to retry once, but guarding Seria right before the big attacks is usually good enough. (I will admit his def ignoring attack makes Lance's BB/SBB negligible, so may RNG be with you in that respect.)

Lance is a plausible option if you don't have Selena or Atro. Also Finkell is completely legit, if you don't have a better RS healer/cleanser who can fill the cost. She'd go nicely with Selena and Atro too, as a backup. :)
