I'd like to see a Grass/Dragon Pokemon; I think it's an interesting combination and I'm intrigued on how such a Pokemon would look.
Grass/Dragon! :V
If you know me, you know I always want more grass types. I would also like to see Dragon/Fairy, Dragon/Bug and just about every other type dragon hasn't been paired with yet.
I agree with these two, I'd love to see how they'll pull of a Grass/Dragon-type. Sure, it would have a fair share of weaknesses (Bug, Poison, Flying, Fairy, Dragon and 4x Ice) but ever since I saw it as a type for a fakemon many years ago I want it to happen sometime.
Also, I'd like another Dragon/Steel-type other than Dialga. It's a pretty cool typing imo.
