Dragons have traditionally been offensively-based, so I think it will go for a mix-sweeper set-up. I decided to make it more special-based because too many Dragons dominate in the physical realm.
Decided to give it a slightly more defensive spread with more HP, mostly because of the other defensive typings that we have.
Same set-up as the Steel type, but with less HP for more power.
Went with more offense, less HP, and less defense, basically thinking "less armor", though more SDef.
I decided to make it rival Jolteon in speed since I imagine it to embody the wind, and since its air, I gave it poor defenses. 110 attack to differentiate it more from Jolteon.
I took the path of those "high HP" fighting types
Went for an Umbreon-like spread, except more offensive power, and slower. Thinking that it can utilize Pain Split.
Can't really think up combinations for the rest of them
