Heroic Razorgore the Untamed - Priest's dragon deck
Consistency: Reliable (expected number of tries 1-3)
I like Razorgore a lot. He is not a hard boss, but he presents a very interesting deckbuilding challenge with several different possible solutions. That's how you make good bosses.
There are two dominant approaches to this battle. One is to use a zoo style deck (usually Paladins or sometimes Warlocks). The idea is to leave eggs on the board and keep hitting them with small creatures to prevent hatching. But Razorgore has two Bloodlusts, so I found this method dangerous.
People also often use Priest with a lot of silence effects, but it basically has the same flaw. So I created this dragon-based deck, which uses a completely new Confuse approach for dealing with eggs and it works extremely well.
Confuse and dragons? Why?
Everything about this deck is unusual and unique. As I said, this deck does not keep eggs on the board. It uses a lot of insta-destroy effects. Apart from Confuse itself, it also uses Void Ripper - essentially Confuse on a body (I bet you barely remember that it exists), as well as Shadow Word: Pain, Crazed Alchemists and Book Wyrms.
As for dragons... well, it is not directly related to the fact, that Razorgore uses dragons as well. Yeah, Drakonid Operative has a good chance to draw something synergetic, but the primary idea was to use a solid midrange tempo deck, since this battle requires minion-based board control and Priest does not really have many options for such decks. Dragons I think is the best one. And as I already mentioned Book Wyrm is another good egg-remover.
The biggest hole in Razorgore's deck is complete absence of AoE. It means, that once you control the board he has no way to comeback. And that's exactly what you want to achieve. Board control. The more stuff you have on the board the better, there is no such thing as overcommitment in this battle.
During turns 1-4 your main concern is to keep initial eggs from hatching. Then start trading in order to gain board control. If you can play Duskbreaker on turn 4, it is usually a board reset. At later stages use high tempo cards like Dragonslayers or Cabal Shadow Priests to get the upper hand and finish the boss.
I already mentioned most of these cards. For egg-control you have Confuse, Void Ripper, Shadow Word: Pain, Crazed Alchemist (who has a lot of other uses as well). Later in the game also Book Wyrm and Cabal Shadow Priest.
Dragonslayer is great for killing Drakonid Crushers and other dragons. Mind Control Tech and Cabal Shadow Priest can get you your own 7/7 drakes. Drakonid Operative was always considered an OP card and he really is, so it is impossible to pass on him.
The first Razorgore's egg will hatch after your second turn, so you MUST do something about it by this time. One drops (Northshire Cleric and Twilight Whelp) can delay its hatch, if played on turn 1. Turn 2 options are Crazed Alchemist, Confuse and Shadow Word: Pain. That's basically what you should keep. With Twilight Whelp you want to keep another dragon, especially Faerie Dragon.
If you have a turn 2 answer, Void Ripper usually is a good turn 3 play and Duskbreaker is a good turn 4 play. Mind Control Tech can be insanelly strong on turn 3, but he is kind of luck based and situational.
AI prioritizes killing mind controlled eggs over everything else except lethal. So only use Cabal Shadow Priests on 0/4 Corrupted Eggs, which will hatch immediately. Don't steal 0/3 or lower, they probably won't live long enough to hatch.
Once you have the board it is useless to keep Mind Control Techs in your hand since Razorgore will never have 4 creatures on the board anymore.
Use Northshire Clerics wisely and try to keep them alive. They are kind of important. Play them on turn 1 if you don't have other way to prevent turn 2 hatch, but if you do, then preserve clerics until you can put them to good use.
This deck won 8 out of 10 games (80% win rate) during my final test. It may lose, if you had a poor starting hand and failed to capture the board. Or if you found no turn 2 answer (which is very rare by the way).
Overall this deck is pretty good and consistent. Its only drawback is that it requires few expensive cards, which have no use in PvP.

Provided win rates are approximate. They are based on my tests and so partially depend on how lucky/unlucky I was during my testing. Also keep in mind, that you need a bit of experience with a deck to use it to its full potential. So first attempts usually have lower win rates, than suggested in this list.
