Not my area of expertise, but I'd say 2x Imperator, 2x Screecher, 2x Prismatic Skywing, 2x Neodrak, 1x Vindrax. After that probably flavor to taste and depends on how dedicated you are to keeping the theme pure. Also probably depends on how rushy you like your BGs.
Been messing around a little with dragons this is what I have come up with so far, it is by no means complete and has much room for improvement. 2 x Dunes manticore, 1 x prismatic skywing, drummer, 2 x whorl, 2 x imperator, 2 x rumbler, 2 x screecher, 2 x sonicbolt, 1 x snogvie, 2 x neodrak, 1 x windrax. spells and equipment all a little interchangeable. I dont play SL all that much so im sure someone with more SL experience could optimize it better. I did fairly well with it, beating some high rank players. I didnt bother with valdac but is an option. Im really enjoying my ST/SP deck atm but when I want a change this SL is something I will go back to, it really has a much bigger potential than what I did with it. Just needs some refining.
