-1 Sir Finley Mrrgglton. Not needed in my opinion.
-1 Jeweled Scarab. Too many unwanted draws (neutral minions, divine favor, etc)
-1 The Curator. Not worth it without the beast and the murloc, which are not good enough
-2 Wild Pyromancer. Too much control for a dragon deck
+1 Chillmaw. Good to defend yourself against aggro, specially followed by a Tirion. Also, a 7-drop, which the game lacks (normally you would have to play a 6-drop and float one mana or coin out an 8-drop).
+1 Book Wyrm. Amazing card, great range of objectives, also a dragon to trigger other effects.
+2 Keeper of Uldaman. Very flexible, buff your 1/1's or control big enemy minions (Rag)
You might also want to consider to swap both Nightbane Templar for Blackwing Technician. The 3/5 is just much more difficult to kill: Shamans can spirit claws+maelstrom portal to clear it and warriors fiery war axe+ravaging ghoul. It's up to you though.
