Re: Trading to-and-fro
Huh, this question seems very familiar. o_O
At any rate, I believe you can trade Gen IV Pokemon to a new BW file without the national Pokedex. I haven't tried it personally, but I did attempt to trade with a friend of mine earlier today. I couldn't trade with him for some reason, though I have speculations it was because I had my Leafeon in the party. I took my Leafeon out and I was able to trade with him... pretty weird. Anyway!
Though as it was said earlier, why not? It should be able to. The Gen IV Pokemon will obviously have the ??? in their number, as usual, if they were traded to the new BW file.
