I didn't mean to cause any problems guys! If I can't trade it, then it's perfectly fine for me. The whole point of my first post was to ask you if you had any solutions for this because I didn't get why it wouldn't transfer. A Jirachi is, as far as I know not even needed to complete the Pokedex? If so, I can live with it being on my Black 2, if it is needed, I'm sure I can find someone on here who is willing to trade it with me (just for the Pokedex entry)! I'm happy about all the help I got and I'm just posting this to let you guys know that suggestions are welcome but you don't really need to get out of your way to help me and solve this completely!
