Medicham is a cheap and very good deck, today in a game i hit 260 on turn 3, its a 4-4 line of medicham PRC w/ ancient trait and a 2-1-2 line of machamp FFI. Pairing that with Strong energy and Fighting Stadium (Also Machamps Ability Boosts all Fighting attacks by 20). The Omega Barrage is very effective in the fact that it lets you attack twice
The issue I have with Medicham is needing 2 energy to attack. How do you get over that?
I have to admit, I'm still pretty skeptical that any Machamp FFI variants (whether Medicham or Lucario EX) can do well in my home state, but I guess it couldn't hurt to give them a try. Not sure where I could find a prototype decklist, though.
I can get you the list I'm using later tonight, if you want that. I can say that it still needs some refinement, but it's working well enough so far. If you're worried about Machamp itself being too slow to get out, then you're worried about the wrong thing with this deck. Between Korina, Sycamore, and Ultra Ball, you're pretty likely to have a Machop on your bench turn 1, and it evolved either turn 2 or 3. But it often doesn't matter that much early in the game. You're still able to do quite a bit before getting Machamp out.
