When the games come out, I'm trading in a set of about a dozen specially bred level 1 critters from Diamond, and getting a starter team made of a whole bunch of random crap I've always liked and wanted to mess around with, but that shows up too late in the actual game to really get used..
Cubone, Dunsparce, Shroomish, and the game's actual starter, Cyndaquil are the ones I know for sure.
Secondary rotation of sandshrew, farfetched, chinchou, Zangoose, Seviper, (I just wanna use the two critters that hate each other together)and a healthy sampling of ma dog's, mightyena, houndour, absol, and finally track down a damn growlithe!
My main party throug Diamond was Sandshrew, Shinx, Charmander, Scyther, Chansey, and a rotating sixth.
It may not be element balanced, but it'll be fun for me, dangit!
