Last time we were talking about this, it seems if nothing else they will transfer your Rainbows from before the re-vamp to the new version.
Which I hope is true as I had 2 or maybe even 3 in there (one of which was a random 6* gift to all players one I pulled, and not sure if I got the 3rd one or not.)
Edit: Ah I wanted to say - I eventually got Tiger lily one of those past few weeks. And I must say, I do like her voice a lot.
Quite adorable and mofu. I can see why Ninjax regards her so dearly, she certainly is cute :3
