keep subame. he is the best normal/flyer we've ever had. pidgeot, fearow dont even compare. Dodrio compares a little, but i still like this guy better.
you should try and get a steroid pichu in the cave north of the fighting gym(2nd gym). it is this monstrous fighting pokemon that goes on to learn Belly Drum.
getting the electric dog would be a good idea. there are a lot of them coming up in the game. i think they are on route 110, which leads into the 3rd gym. i could be wrong though.
you can drop that grass piece of crap if u want. i had one, and its only good use is cut and flash. lol. it does evolve into a grass/fighting form. so if that appeals to you, than its ok.
getting an abra would be a good idea. even though you can't trade to evolve it to kazam, kadabra still kicks this metagame's ***.
