Main Team - Diamond, 1st Time

[Conman]

Ok, I just got Diamond and I need help making a good main team. Most of these pokemon I chose where becuse of their type and how cool they look (I didn't have time to really think it out). I would like pokemon I can actual get/catch in Diamond and no moves I have to breed for. Trading for evolvations and items shouldn't be a problem with WiFi.

Piplup - Empoleon @Leftovers
Modest (+SAtk, -Atk)
- Surf
- Ice Beam
- Grass Knot
-

Shinx - Luxray @Choice Scarf
Hasty (+Spd, -Def)
- Discharge
- Crunch
-
-
*Luxray is one of my fav pokemon so I hope I don't have to remove it*

Starly - Staraptor @Choice Band/(a berry for Pluck)
Adamant (+Atk, -SAtk)
- Brave Bird/Aerial Ace/Pluck
- Return
- Agility
- Steel Wing

Budew - Roserade @Sun Rock
Modest (+SAtk, -Atk)
- Sunny Day
- Solarbeam
-
-

Rhyhorn - Rhyperior @Choice Band
Adamant (+Atk, -SAtk)
- Earthquake
- Break Brick
- Avalanche
-

Sorry for this double post, but I really want help on my team. I am not good at waiting. I have started now and I really need to know if these natures and pokemon are good, atks can wait cause I am still in the beginning. But natures are given soon as you catch em so I don't want to be wasting my time trying to get a sucky nature or wasting my time training a bad pokemon. Basically this is a bump, so...

BUMP

Look around to balance your team.
