Hmm,  lemme see...
Typhlosion
Jolteon
Umbreon
Salamence
Larvitar/Tyranitar
Dragonite
among others...
Like, Rhiannon, first I look at their appearance, then I get one of each type for the team (which lasts until the end of the game).  Until the team isn't fully built, I just use fillers until it does.
My teams usually are:
- Fire-type
 - Water-type
 - Electric-type
 - Psychic-type w/ Ghost and Dark moves or Dark w/ Psy, Ghost and Dark moves
 - Dragon-type
 - Last one varies, just to fill the last slot, usually a Steel or Rock-type
 
I like them fast or tough, preferaly both...
The main one is always 5 levels higher than the others, in case something bad happens (not likely).
[Edit:] The new pokemon look promising, though I didn't picture Lucario as a Fight/Steel type when I saw the movie...he looked Psychic to me.
