I can hardly remember my first Pearl team, so i won't even try to remember my older teams.
But in Pearl i'm pretty sure i had
Torterra <-- This thing was a real beast, it beat half of the Elite 4 on its own, this includes Flint. My MVP back then.
Mismagius <--- I think the moveset i gave it was probably the worst one possible, it was still having Astonish when i faced the Elite 4 =D
Octillery <--- I'm pretty sure i had one, but don't ask me whether it was good or not
Garchomp <--- I last-minute-trained me a Garchomp up before the Elite 4, because i just couldn't beat them and i read somewhere that that thing pwnz.
Palkia <--- Yes, i used Palkia back then, but for some reason Torterra was a lot more awesome, and not even in terms of looks.
Uxie/Azelf <--- I don't know which one i had, i think i dumped the one i was using after the Elite 4 pretty soon.
Before i had all the legends, i was having a Kadabra, a Machoke, a Staravia, and maybe some other stuff as well. And there was a Luxray that was pretty high-leveled, maybe i used it over Uxie/Azelf, maybe not, i don't really remember...
