My team is about to hit 50. I'm hoarding mithril for the anniversary events. I'm doing well, but am not sure what to do next.

Tyro (w/ Sentinel's Grimoire) and Bartz (w/ Trueblade of Legend) are my only characters with SB granting Relics.

I'm using Cloud, Larsa, and Rydia as my other three, without character specific relics. I have Cloud and Larsa's MCI. I don't have any of Bartz's MCs, as I pulled him from the Hall of Rites after I got his Relic.

I have Sephiroth's Gloves and Twin Lance. Should I get Seph or Squall from the Hall of Rites to use their relics? I feel like I'll run out of steam shortly if I don't get more O/S/B SBs. I've been hoarding for the upcoming anniversary, but 2 1/2 weeks is a long time to not "plug" the relic hole in my team.

Thanks for your feeedback.

edit: I've got all the MC1s from the VII event.
