What is a good team for the battle tower in Pokemon diamond?

I would Reccomend the following team

Starmie (timid nature)- Thunderbolt, Ice Beam, Psychic, Surf

Dragonite(not yet decided)- Thunderbolt/Thunder, Ice Beam/Blizzard, Earthquake, Ariel ace

Heracross(adamant)- Megahorn, Stone edge, substiture, close combat/Brick Break

That is a pretty good team... but instead of dragonite i would put a latiOS... latiOS outclasses all dragon types and has a good moovepool... but other than that starmie is a great Pokemon to have aswell as a herracross

Hi my expert team is latiOS with soul dew he knows :luster purge , thunderbolt , dragon pulse , and recover.

then i use a froslass with life orb to power up her mediocre atk she knows:wake up slap , blizzard , ominous wind , and destiny bond.

Then finally porygon z with focus sash he knows : signal beam , discharge , tri attack , and recover and with that team i am now rank 4 on wifi with one loss.
