I've been experimenting with 1 DP Machamp in my version and it is truly amazing to Revenge with the lv. X (because it does 130, the magic OHKO number). The SF is great early game for easy OHKOs and late game if you can power up for Rage, but it doesn't have much in the way of 'comeback' ability in between those times, whereas the DP one comboed with the lv. X certainly does. In fact I'm convinced that it is the lv. X that really makes Machamp into a potent deck, and also what elevates it above a cheap one-trick pony (since you have to time your level ups wisely, do a lot of potential damage calculations beforehand, hedge some risky bets with No Guard, etc.).
Also, Premier Ball with the lv. X is amazing for recycling purposes. Whenever you play the lv. X you're probably going to be getting a OHKO in suicide fashion, although you may get lucky and pull off two such OHKOs before going down, and when you do you can just immediately bring it back to level up your next Machamp and get yet another likely OHKO, especially if that Machamp happens to be from DP. Most decks can't take losing their main attackers so easily and in such quick succession. All that being said, I would consider getting a second Premier Ball in here somehow. I'd also find room for an Azelf to get that lv. X out of your prizes.
One thing you could do to accommodate these changes is drop the Blower (because by the time you accumulate 2 in your hand, they probably won't even have any Basics on your bench to easy-kill, and I'm assuming that is the primary reason you're running it). In the 2 extra slots you could add 2 more Uxie, or one Uxie and its lv. X. That card will help you get the turn 1/2 Machamp just like it helps Kingdra so much. The lv. X also would come in handy for mirror matches.
