HeartGold Team suggestions

[lucy_goosey]

I've had SoulSilver for ages and I loved it so much I decided to get HeartGold.

Anyhoo, I'd really appreciate some suggestions for a new HG team since I'm rather lazy and can't think for myself ;)
I have decided that my starter will be Chikorita (I had Cyndaquil on SS) and I'm tossing up the idea of having a Togekiss, Espeon and Jolteon.

So, some suggestions for a team of five or six would be appreciated. Only Pokemon available in HG though, please, because I don't really have a convenient way to trade.

EDIT: Because I have nothing better to do I thought of a team:

Meganium
Togekiss
Arcanine
Jolteon
Espeon
Donphan

I'm not too sure about Donphan because I've never used one before. Although, I like having a Ground type on my team now that I've used the Garchomp line in Platinum.

If you list their movesets it's much easier for people to help you (even just their planned sets are fine if they're not fully trained yet.)

I'd Gliscor instead of Donphan, since Gliscor has a better movepool and also a nice typing.
