I was thinking of going for gold buttons with 10 card reveals, but I might give your suggestion a try too I still have around 200 card reveals from the last time they put them up with the N gacha bundle. If they do put them up for sale with peros again at some point, then I have nothing to worry about, but if they don't, then those ~200 card reveals that I have might prove to be invaluable...

On the other hand I really want that SR card (so pretty ^_^), and I have already prioritized her over just about everything else at this point. I should be able to stay in top 1000 comfortably even without peromins or glasses, so I fed those to Kurito...but she isn't being very nice to me
