Gen 5 Only Raindance Team

[OmegaNemesis28]

Hi. I'm looking to build a rain dance offensive team consisting of ONLY generation 5 pokemon.
I'm not asking for someone to build a team for me, I just don't know where to start. I just need some help getting off the ground.
I had a nice gen 4 team that I would always play with that I made by taking my favorite aspects of different rain dance teams that I've seen or read of and spliced them together. I can't do that now, and I don't see any generation 5 only pokemon rain dance teams around either making this difficult.

What should I be looking for with these new pokemon?

Note:
I'm not making this team to play competitively like with smogon or anything like that so the whole swift swim drizzle ban doesn't really apply. I'm just doing this with friends.

Ferrothorn gets great protection in the rain and sets up spikes so you'll want him,
Jellicent is a great new water pokemon to consider,
Alomomola gives good support to your other team members, mainly in healing, making it good for double battles and it also gets hydration,
Seismitoad with swift swim allows for fast earthquakes and he can set up rain dance too,
If you're using legendaries then Tornadus and Thundurus can be good for setting up rain and 100% accuracy thunder respectively,
Galvantula gets 100% accurate thunder and can use bug moves to take out grass threats.

That's seven so you'll have to cut one out. I'd suggest Thundurus. But there are loads of other options to consider.
