I've been mainly focusing on catching Black Gold quest moga, so I've got a pretty good assortment but I've only evolved 2 guys so far. Think I'm stuck in that quest pending much leveling though, so I'm starting to collect for evolutions.
So far 76. I'm picky with what i want, i normally go for ones that appeal most to me. Some are duplicates from when I started the black gold quest, but even then I try to limit how many I have of just 1 moga if i'm not using it for evolution. xp
