Rate my Pokemon Black & White Double Battle Team?

Great team I can't be much of a help because I'm not familiar with teams made for double battles. I suggest you should put Leftovers on Amoonguss since that what people usually put with substitute. The only thing I would change is replace Psychic with Bug Buzz for the STAB but I'm guessing you put Psychic on him in case the opponent sends out a fighting type to kill Carracosta. Yeah that's a pretty good team and there won't be any Pokemon that can cast weather permanently if I remember correctly so yeah good luck at the Pokemon vgc this summer .
