im gunna try and beat diamond again, but i dont wanna use my same team (starter+luxray+staraptor+roserade+dialga+lake spirit). But i dont know what other combinations would allow me to move to and through the elite 4 without a major problem.

I saw pokmon.marriland.com uses a vespiquen, rampardos and kadabra. I experimented through the game, and i dont want to use torterra cuz i suck with it, so id prefer monfernape (my favorite) or empoleon+lucario(my second favorite). But even after that im not sure what other pokemon to add, i can get kadabra easily if i choose chimchar.

Also, if you have a suggestion for a team, it would be nice if you had a rough moveset. IF not it doesnt really matter though, since i usually just go for damage moves anyways. Thank you all in advance
