Well well well, my second attempt at the White 2 Nuzlocke is going much better. :)
I've just beaten Burgh and got my capture from Route 4. Now I'm training before going any further.
Cerulean | Ecruteak | Viridian | Cianwood
Purrloin [Cinnabar] | Pidove [Pewter] | Audino [Olivine]
Dunsparce are absolutely amazing for the challenge. One Electric type and then one other random type (preferably a duel flying type) and I'd say I was content with the type diversity. :) I don't think I'm going to evolve any members of my current team much further - I prefer all of their current forms much more than their evolved forms.
