User blog comment:Emilyc6677/Why would ajhq make an adventure that can win you betas and spikes?/@comment-32197189-20171226083944

Reason for the adventure:

It's member-only, to encourage membership purchasing. They've got to have someway where 'newbies' feel like they have a hope, or chance, to get something. They give them out just enough to tickle your 'I want rares' senses, but not enough to make you go: Ooh, sweet, free rares!

Colour order? I'd LOVE to know that myself! I'm assuming that ppl just wanted a black one first, and over time, it slowly evolved to an order. But I'm with you in curiosity over that one.
