With Eviolite Dusclops outdoing what Dusknoir can do in walling potential, Dusknoir has dropped to NU.
I forgot that item *face palm*
I also have a great rain dance team in mind (how original >_<). It involves a Politoad lol
I think its better then most. I'm not going to post everything because that will take too long but here are the pokemon:
Politoad (defensive), Toxicroak, Thunderus, Ferroforn, Latios/Latias (I'm thinking Latias as it takes more hits). My last pokemon is between, Ludiciolo (makes the most of rain dance and if or when Politoad goes down, Ludicolo can keep the rain dance and it makes the most of it while rain dance is there), Virizton (just a solid sweeper that can take a hit and it loses its fire weekness) or azumaril (aqua jet, STAB and in rain will take care of most pokemon). There is one more pokemon but I doubt it will be a viable option. Swampert. Its a strong pokemon, does well in the rain but I think Azumaril will be the better option.
