I'd like to add Moonlight Tsukiyomi, Svarog, and SSR Cybele to this list...
but after you reroll for some of the better kamihime, then you'll probably want to get gems as much as you can cause there's a lot of R kamihime (some are quite good like Konohana-Sakuya and Zephyrus) sitting in there.
a good Reroll would have 2 or more of the SSR kamihime/eidolons mentioned
