Is this a good Pokemon team for White version?

That is a perfect team, but you have a lot of dragon types. Take out Druddigon for Scolipede. I have a good move set with it. The ability should be poison point, item rocky helmet, moves: Steam roller for flinching, venoshock for double damage on a poisoned pokemon, iron defense, and baton pass. the other pokemon's HP will decrease rapidly by the damage of poison and the rocky helmet. It is a pretty fast pokemon so you could give your defense stats to Krookodile. Make Krookodile's item to be a dragon fang and Hydreigon should learn flame thrower for ice types. Get rid of dragon rush. He is more in to the special attack power. Its item should be a charcoal for fire types moves or a silk scarf for hyper voice to knock out pokemon in triple battles.
