Just completed the National Dex after I traded Semipour for Yancy's Spinda. It wasn't really that challenging thanks to so many Pokemom being viewable in B/W2 for the Pokedex and just trading on GTS. Which I actually like. For a while I thought I wasn't going to get a medal, but then I realized that I needed to get the diploma first.
Now I'm going to focus on getting the battle medals.
