Pokemon HeartGold Version

Could this be a good team?

I have 7 gym badges and am wondering how good this team will be when all the pokemon have evolved. Are any suggestions on move sets or improvements? Please rate my team also.
1. Lucario
2. Garchomp
3. Metagross
4. Tyranitar
5. Dragonite
6. Kingdra
I know there are 3 dragons but I want move sets to combat this. I made this team by trading the level 1 of each pokemon (got eggs by breeding) into my game from platinum as soon as I started a new game.

I'm not having trouble on the gyms ( it's quite the opposite) I just know it's not too late to make changes. My strongest pokemon at the minute is Lucario, but they're all really good.

Well my team is a:
Cydaquil
Red Gyarados (from lake rage)
and well a Bellsprout but i would go with turtwig if you have pearl/diamond/plat.
Onyx and
a soon to be Togekiss
srry and an Ampharos (mareep)
I've gotten all 8 badges with them

I would keep Metagross,Dragonite(for sure), and Kingdra, maybe Lucario
