@maotd So who will you use rainbow coins for? Now that you got Kerria?
That's a very good question I asked to myself just after Kerria. I have a deep hesitation. I want Saffron because she is S tier and will be very helpful for my Counter team. But I also consider Snowdrop to build something around Kerria. With Lavender Valentine reissue approching, I may have a nice base to support Kerria on harder fights.
There is so many rainbows and not enough R-medals to choose everyone
