My current plans are to build the following team:

1. Typhlosion. Starter, covers fire element, and can learn Cut.
2. Noctowl. It can learn a good array of psychic attacks, and can learn Fly and other flying moves. Potentially replaced by Lugia later on, who covers the same bases
3. Quagsire. The fun water type that's also my solution to electric types, and will get the better 2 Water HMs (Surf and Waterfall)
4. Machamp. Earliest fighting type available in the game, should be invaluable for Whitney and elite 4 Karen Plus he can learn strength and rock smash (i think)
5. Spiritomb. The elite without weakness and bane of all psychic types.
6. Abomasnow. Ice covers grass and dragon, while grass to beat water.

Should be pretty good. All i'd be missing would be rock climb, whirlpool, and flash from the basic setup, and those are more limited-need anyway. Should also cover me against most elemental possibilities, especially the ones that are more prominent in this game.

What are you all planning on?

(note, i am aware of the official thread in the game specific forum, but it seems to be rather dead, so i'm placing this here)

Right now my SoulSilver team is as follows:

Lvl 42 Feraligatr

Lvl 40 Fearow

Lvl 39 Red Gyarados

Lvl 39 Graveler

Lvl 38 Haunter

Lvl 38 Vulpix

I have 8 gym badges, and have cuaght Lugia.

Feraligator
Ampharos
Togekiss
Magmortar

and two slots left to be decided. I gotta say, this game is a blast so far, and pokewalker was such a good idea, it's not even funny

I think I'll build this team:

1. Feraligatr
2. Red Gyarados
3. Ho-Oh
4. Giratina
5. Spiky-Eared Pichu
6. ???

Well, Pichu and Ho-Oh are there because I don't have any other good ideas right now.

Right now. My party is Graveler, Flaaffy and Bayleef.

Typhlosion
Blastoise
Ampharos
Alakazam
Tyranitar

My sixth member is as of yet undecided. Any suggestions?

Seems to me like you could use a fighting type also. Tyranitar can have ground-type moves, correct?

Lucario would be a good fit, maybe...

Yeah, he can use ground-type. I was thinking maybe someone flying, though.

When in doubt:

Dragonite

Hmm, that might work. I will deliberate further once I get my hands on the game, methinks.
