In my opinion save it. We don't know when for sure but a major event is coming up soon called Rift of Recollection. This event lets you go back and get characters and memory crystals you might have missed from earlier. Attached to this event are relic draws referred to as the Super Soulbreak Celebration. Most speculation puts this event right around Christmas time Each banner is going to have at least one Super Soulbreak weapon on it (there are 5 phases with Cloud, Squall, Rinoa, Paladin Cecil, Cloud and Tyro each getting a weapon so there will be one banner with 2 SSBs on it). The rest of the relics on these banners tend to be extremely good and highly sought after ones. My advice is to save that Mythril for the SSB Celebration and dump it all there.I got Grand Glove too... And a Cyan sword and Dark Cecil armor.
i have 100 mithril saved up still too... Not sure if I want to use it on any of the relic pulls that are out now or keep saving it for something else.
Pull on the new FF9 Banner with Eiko's relic. It's two of the holy trinity of AoE Heal/Hastaga/Stoneskin. I just did a 11 pull myself and got it, first relic I've pulled for that I got! So happy, just got Stoneskin to go so now I'm saving for every Thyrus banner.Eh I'm still new, so I'm not even quite able to get all the MC from events yet. For progress forward it might be better to just pull tonight for some mage gear (as I'm doing "ok" on retaliate for a meta).
Eiko's Flute is really nice but was redundant for me so I didn't pull on the banner.Pull on the new FF9 Banner with Eiko's relic. It's two of the holy trinity of AoE Heal/Hastaga/Stoneskin.

I decided that Eiko's Cure+Haste relic is better than Sazh and Red XIII's Protect or Shell + Haste relics since you usually have to recast Protect and Shell on the harder bosses so I'd rather take the abilities and not have to stress about building limit break gauges or death. I'll also be using the AoE Cure+Haste on turn 1 so any unmitigated damage will get healed up rather than needed to S/L.
