Sorry about that, I realized that about a day after I sent you the message. Eitherway, either way according to the Unova Dex,#300 is Genesect, a Pokemon I won't be able to get, its a WiFi event only, and I don't have WiFi - so I can't trade for one. So I will only be able to play the game with 5 Pokemon.
Thanks again. I'll have to wait until my next Pay Day on October 1st to buy another Black 2 game.
