I like Rapidash myself. Everybody wants a Charizard, and while 'Dash doesn't have Earthquake, it can use Iron Tail, along with the good ol' Sunny Day-Solarbeam combo. Bounce is good to avoid any E-quakes from the enemy, and plenty of agility to dodge those evil water moves. It's got Flame Wheel as well, and also a few tricky moves, like Hypnosis, Charm and Baton Pass.
