Last event girls were 1000/400/200, which felt like a better value for the lower SR and R. The wording sounds like they won't be available as Shards rewards again, but we'll likely see them in revival gatcha. I wouldn't pick them up unless you really like their art.

Ex Wilds are hard to come by outside of Shards event, so I would advise skipping the R and SR wilds. Even if you aren't interested in Ex leveling, Feeding Kurito Ex wilds one at a time will net you way more than 1.33 SR wilds on average, although I would advise feeding something else with an ex wild to push into the 1501+ point bracket, to be most efficient.

Lastly, keep in mind that there's no guarantee what the trade prices or girl/item availability will be next time.

Honestly, it doesn't seem to matter much which of the new cards anyone gets. They all have nearly identical bodies, faces, and totally vacant expressions. Only the hair/clothing is different. So you can't really even pick a favorite, and the only thing that really separates them is the max SED. If you can get the SR, great...if you have to choose between the two Rs the one that costs more shards actually has less max SED.

I regretted not being able to get Damocles last time. I probably won't get her this time either, and I'll be stuck with crystal crotch catgirl and/or the other R.
