PerseusRad, catch yourself both a Plusle and a Minun. The two must fight in three double battles together to determine which one will be a permanent member of the team-- it depends on who wins the battle for you by knocking out the last of your opponents's Pokčmon. The one who gets the "best two out of three" will be in your team permanently, while the other will be boxed. Whichever one you end up with, it may not have more than two attacking moves at any time.
I don't have a signature because I can't think of anything interesting to put in it. But hey, better than an enormous ugly banner that takes five seconds to scroll past, right?
