Setting up a Sandstorm team in Pokemon Pt/HG/SS?

Go to a href="http://www.smogon.com/dp/buildteam/" rel="nofollow"http://www.smogon.com/dp/buildteam//a then select the pokemon you want to use. I recomend the 4 that you said, Hippowdon and Flygon. They are great pokemon and it will make a great team. If you click "Moveset Analysis" on a pokemon you wish to use it will tell you best movesets for that specific pokemon. (: Hope I helped.
