Im gonna start a new run on Soul Silver. Just bought another DS aswell, so I have a 3ds and a ds now. I also have white2 and Platinum. Question: Is it possible to catch some pokemons on my new soul silver run, and then go to a pokecenter and trade them with my other ds to white2/platinum and then trade back so they can evolve? Can I do it in the first city if I catch something I want to evolve?
