Like another has said, 3000DMM for 200 rainbow coins is like a cheaper pick your 6* waifu ticket being that I'm at 211. I went with it and my 11 roll netted a new gold in Wood Sorrel for me as well as a dupe Swimsuit Chocolate Cosmos. As for the coins, I think for now I will consider it a future investment and wait through some events to see if there eventually comes along a rainbow that I know I must have.

Did any of you reach 300 rainbow coins with this deal and decide on a choice? Who'd you go with if you did?
