You can try EV training for fun, and Wonder Trade away the ones that don't fit the bill. You can then just Wonder Trade lots and accrue lots of Pokedex entries in foreign languages... along with a crapton of Bidoofs and various Stage 0 bug Pokemon.

*Seriously, I've been Wonder Trading away atheist, insufficient Porygon all morning and I've gotten more Bidoofs than all others combined, and probably about 80% either Bidoof or female Wobbuffet. Sent away the Porygon, just got a Scatterbug or whatever, sent it away, got Caterpie. Sent Caterpie, got female Wobbuffet. Sent female Wobbuffet, got a Japanese female Wobbuffet. Sent her away, got ANOTHER Japanese female Wobbuffet.
