Event Pokemon or Pokemon I've never seen in any of my games (like the legendary dogs for example). I have most event Pokemon from either events I got them from (Mew, Deoxys, and I think I have Jirachi) and traded with someone for Celebi, but I have no idea how I will be getting the others yet. I'm going to see if anyone I know has them I guess and if not unfortunately those entries will have to be blank.
I have a DS lite and still haven't had problems. I know setting up the router in general was annoying but everything has been fine since. The legendaries I would have issues getting are ones that I don't have and can't catch. Hopefully someone would be willing to trade and trade back so I can get it on my Pokedex somehow but I'll worry about evolving more Pokemon first.
