Hearthpwn

Hi beautiful people! I'm new to HS, playing almost 3-4 weeks. Was stuck in rank 16 with my Tempo Mage. Since I purchased all the DLCs, it was not problematic for me to craft  Thijs's dragon priest. It has been 2 days, in total 50 games, have 55% win rate and almost rank 12. The toughest opponent for me are RenoLocks. Enjoying the deck very much! It is very fun to use opponent's cards against him/her after stealing them with Drakonid Operative :) Thanks a million Thijs :)

Replacement for Twilight Guardian? I have zero copies of it and I dont want to craft them since they will rotate out soon...

they are kinda crucial and they will rotate in around 4-5 months so you can consider crafting them

Is 9 dragons in 30 cards enough to trigger all the battlecries? 

That's about all you need unless you get really unlucky.

Would Ragnaros the Firelord fit in this deck?  Just wondering because I find myself coming up short sometimes.

Could swap out a Twilight Whelp for it maybe.

I tried it. It seems good. (small sample size though)

You should not run out of firepower in this deck. You have two Drakonid Operatives and two Netherspite Historians to pull late-game cards with if you need them. If you are having trouble, save Brann for it. Bran + 2x Netherspite Historians is likely to give you more than enough late-game to overwhelm most traditional control decks (except stuff like Jade Druid and Freeze Mage).

Very solid deck, although leaving out Dragonfire potion might be a surprise, I usually find myself sitting on mine for far too long.
