Hello, I've seen this time quite a few times as well as watched some of your matches and I must say this team is fabulous! Anyhow, there are a few slight adjustments which you might want to consider for the team:
First off, you should invest a bit mroe speed in politoed, nothign more then 20 ev's or so to outspeed jellicent, skarmory, scizor, and a ton of other pokes in that speed range. Secondly, and also my final suggestion, would be to give dugtrio memento over rock tomb, it help's agaisnst set up sweepers which your team can be threatened by because at +1 a lot of things otuspeed scarf genescent and definetly at +2 they will. This gives them a free reign of terror agaisnt your whole team assuming they have boosts in attack or special attack which memento will cancel out. Anyhow besides these minor adjustements your team is great, LUVDISC'd!
