1. No Technician for Roserade, it doesn't even have a move boosted by it.
2. If you want an offensive Milotic, personally, I would go with Hydro Pump over Scald. The burn chance isn't as useful for an offensive Pokemon that needs sheer power.
3. For Houndoom, I've personally always preferred Fire Blast to Overheat, due to the almost as high power/accuracy, but with no nasty stat recoil. But that's up to you.
4. On Umbreon, perhaps consider Toxic or something over Payback?
But everything else looks good to me. Not that CK won't tear it apart, of course....
