Looking at blaziken, He looks pretty good. But if you're going to ahve him on teh field at the same time as groudon, then his earthquake really isn't necessary. i would replace it with Fire Blast, a good powerful fire move that would be amped up by his fire traits. If groudon is going to be out, then protect might be good on blaziken. However, the only plus side to sky uppercut is that it hits pokemon that are currently using fly. natrually if they're using fly, sky uppercut wouldn't do much anyway. I would suggest a stronger fighting move like brick break. It's strong, and it gets rid of those annoying walls like barrier and light screen. It would be of greater help than sky uppercut.
For Groudon, Earthquake and solar beam I think are keepers.His sun light effect is good for Solar Beam. If you really want to replace Erruption, then put in it's place a good fire move like Flamthrower or Fire Blast. i would suggest, however, that instead replace hyper beam with either fire blast or flamethrower. because erruption has good strength as long as Groudon's hp is fairly high, I would suggest keeping it. It can hit both the opponents pokemon at once, which is always a good thing to do. hyper beam isn't really needed, since you're helpless after you use it, and hyper beam just isn't teh kick butt move it used to be in days of old.
Looking at the pair now, I'd sya they're pretty descent. A good combo move like proteect and earthquake I never would have thought to integrate into my own team. ( got annoyed when the cypher Admin, what-his name, kept using it on me and didn't feel like immitating it.;) )
