I'll brace myself for the glares and pitchforks, but my 5th roll ever (back then I did single rolls, either out of pure noobery or impatience, or both) was a Black Baccara. This was long before I had any idea just how rare rainbows were.

Since then I gladly paid for that 11 rolls + rainbow package. I chose Cactace and got a Camellia, so totally worth it in my book.
