Okay, so let's analyze things based on appearance now, shall we?
It's apparently a Rock/Dragon of some sort. Now let's assume it is capable of learning Outrage and Stone edge, which it probably most likely will. Knowing Garchomp(which is an uber competitively, as you already know), I'm thinking it was at least be roughly what Ononokusu would be, to a point. At least I know that it'll be deadly in a Sandstorm team of some sort, with or without Sand Veil due to immunity from the Sandstorm. I don't know if its going to learn Dragon Dance or Swords dance(by the looks of it, probably the latter), but knowing either one would probably automatically place it in the spot for OU. Unless, however...its base speed just so happens to be terrible, which is actually quite common amongst rock types(unless it's Aerodactyl or probably Kabutops, but I'm not sure). Then yeah, that would be it's one major weakness there, which then would make it more useful in a TR team than Sandstorm in that case.
Well....I guess that either way, it would be dangerous in some manner. If it has a high base speed, then I know it'll be the next Garchomp. Without it, it'll probably just be a more bulkier Flygon or something.
