Need a little help for my team.

[Keynir]

Ok, I have 5 pokémon in my team right now. But I don't know which will be a good 6th one to 'complete' the team.

The 5 are:
Empoleon
Staraptor
Luxray
Lucario
Roserade


As a sixth I was thinking about Blissey, Garchomp or Bronzong maybe. But I have no idea what will be good or bad xD.

I hope someone could clear me up on this ^^.

A Bastiodon would be a good ground type. another one would be Hippowdon, for Sandstorm.

[Keynir]

Hmm, I can't get a Bastiodon on Diamond and I don't really like Hippowdon, since it doesn't appeal to me xP

But thanks for the help :D It's very appreciated ^^

Garchomp is a good choice.

Go for Garchomp. He's awesome, plain and simple.
