This is a team I have been using to great effect on the smogon battle sim. It is netting me probably a 65-75% win rate, and since I'm brand new to this that isn't too bad. The main issues I'm having are with the Rotom forms, which give me all kinds of grief and seem to stick around forever; that s.o.b Ferrothorn (although I don't think that can be helped, it's just my inability to predict him correctly and get a fire move off); and not being able to sponge hits from the likes of Landorus-T, enemy Terrakion etc. Donphan is great as a 1 time spinner and stealth rocks user, but he just doesn't have any longevity or real walling power. Jellicent is a little better, but I have barely used it as a spin blocker, which makes me think maybe putting Chansey or a more bulky special wall in its place would make sense. Any help I can get on this team I'll appreciate.

This team works wonders with having switch advantage, all because of the monster that is Genesect. Using U-Turn as they expect the revenge kill and getting that extra type advantage is incredible. Terrakion with his scarf is invaluable as well. The two of them are responsible for almost all of my wins. The main problem, as I said, is walling certain pokemon and Rotoms. Thanks.
