Picked up B2. Now I'm in Castelia, after beating Burgh.

Magnemite is fantastic. I also got a Koffing, for the first time in ever, and he's actually performing pretty well. When I get more Chesto Berries, i might go for a Rest/Toxic sort of deal.
Now I'm trying to find an Eevee in the park, or figure out where the gift one is.
