My old silver team (before i thought it would be a good idea to yank out my silver cartridge while the game boy was on and erase the game ;_; )
XD I kind of had the classic "Gary Lineup" going with Pidgeot, Alakazam, Rhydon and Arcanine, except I replaced Gyarados and Exeggutor with, in my opinion two superior Pokemon of their type; Starmie and Vileplume.
My new Silver lineup isn't as good ;_;
Lv50 Arcanine (Traded it from Red)
^ I beat all the kanto Gyms with that team, even Blue XD I don't work very hard to train, but I teach them good moves.
Also, I have a Lv55 Espeon that I don't use as frequently, but is nonetheless a valuable ally for some things.
