[@Pikmin Eye] Alright, nicely posted. Yupp, this seems to be a good plan. Except a, hah, tiny detail. You still smell of Super Repel. Those Pokémon you want to train against before moving on is going to be actively fleeing as soon as you're within, like, 20 meters.

Suppose it is possible for you to stay at a (quite considerable) distance and have Nincada train outside the Repel range, buuuuuuuuuuut that's pretty impractical. Another option is to wait out the effect by resting to train after, but are you that patient a young man? Haha.
