We also still need to put out how certain Pokemon (i.e. Scyther, Dusclops, Onix, trade evos in general) are going to evolve.
After much discussion, RB and I decided it'd be wisest to have trade evos be a level-up thing instead, or merely a deal of "here's the item you're supposed to be traded with" depending on the Pokemon (most notably atm, Onix -> Steelix)
Just so we get that out of the way early before I have a Dusclops and it suddenly needs explaining when everyone goes "You're evolving into Dusknoir totally wrong, UE!" :P
