Well, i would go with the grass type. It will at least get you started, and later on you can get some really great fire and water types. There aren't very many strong grass Pokemon in these games. If your looking for a good way to start, go with the grass!

Well, Pokemon Battle Revolution doesn't have starter Pokemon. I was disappointed by the non-roleplaying actions. You upload your Pearl, Diamond, and or Platinum Pokemon onto the game.

All of the starter Pokemon are the best
