Clefable [F] (Opener)
Reading through your team, I noticed that you had a lot of reliance on Leftovers. I think that this poke could do a lot more good with either a Miracle Berry or a Scope Lense, especially considering it already has a recovery move and T-Wave. I like the set, but I would definetely change the item.
I am a sucker for the EQ/Rock Slide/Rest/Sleep Talk set, but this would work on half the pokemon out there. This pokemon lacks any sort of recovery, which could very well be the end of it, but it could do very well if used properly at the end of matches as a warm up sweeper for the Machamp. Submission and no recovery move is bad, I'd try Body Slam in its place if you are going to insist on attract.
This is a dirty fucking set, I hate it. Starmies are so damn cheap its annoying. I don't know if people do this typically, but with cheap pokemon like that, I like to give them Focus Bands, just because if they hang on, whomever you play usually gets so frustrated they slip up. Usually when you hang on, you just recover and end up killing a couple more pokemon. But Miracle Berry works, especially because Focus Band only end up works a third of the time or whatever the percentage is.
Since you don't have a hazer, then yes. This should work out well.
You have so many attackers like this, I would consider taking out the Clefable and putting in a spikes Fortress. You could switch around against the rest of their team, and having the spikes up would give you a monstrous advantage with a team like this. Umbreon is nasty, but I'd maybe replace D Edge with something, but I don't know what. A cursed up Double Edge is going to do some damage, and you may end up hurting yourself relying on it w/o rest. I'd suggest swift, because a cursed up umby with swift I'm sure is really annoying to fight.
Ghost HP is a waste. A Psychic is going to rape you before you kill one with Ghost HP, and all the pychic types worth having have recover moves. I like the Leftovers/Reflect/Light Screen combo, nobody is really expecting a defensive Machamp. I'd throw in either a fire blast or an EQ over Double Edge.
A lot of my suggestions are made up on the fly, so sorry if they suck.
