I'm more of a Ghost, Normal, and Water girl myself. Ghost because all of the Pokemon are creepy-cool and useful to boot (Yay for Gengar!), Normal for the huge movepools (useful for in-game teams), and Water because there's just so much I can do with one Water-type. No team I've ever created hasn't boasted a Water-type in some way, shape, or form, even Netbattle teams.
