When WOG hits, I'd recommend adding Deathwing, Dragonlord. An 8-mana 12/12 that has a beneficial deathrattle and benefits from Dragon Consort is nothing to sneeze at.

I would make these changes:

-2 Aldor +1 Lay On Hands +1 Uldaman

-2 Argent Squire +1 Brann +1 Jouster (the 1 mana neutral TGT dude)

That gives you a more viable 1 drop, Brann synergy, Uldaman flexibility with Hero Power for example, and Card Draw + Heal.

Maybe also try Finley for something like Armour Up or Heal or even Lifetap.

LOL why did you post this!? this is a premade deck in the game allready...everyone allredy has this in there game..am i missing something?

Why Argent Squire?

I lack Chillmaw and Ysera myself - which i am aware of are staples for many a Dragon Deck - so I added Chromaggus and Dr. Boom in my case.
Still this deck in my opinion just does not work. I never even get to summon the big drakes since I seem to lack early game defenses too often (which is where Dragon Priest has a huge upper hand with Wyrmrest Agent and Twilight Whelp), combined with midgame removal and card draw (where priest has the Northshire Cleric and Museum Curator).

I gave the deck quite a few tries, thankfully on Casual, but I keep losing.
