HOLY FUCK!! This WORKED!!! Tried Druid, Priest, Paladin and Warrior. Almost had it with a cheap mill warrior deck but it just wasn't happening. This worked on the 1st try. Despite him getting Stand Against Darkness  and Level Up! ...

Nef is SO RNG dependant, if he has a shit hand with few minions and no drakonids, you're pretty much set.

Although the power level of spells has increased substantially since the adventure and since the deck was made, but it still works.

Best deck by far on front page... I sunk so much time into this boss and his RNG. Great deck thanks

Great deck! Worked first time! Although I had to change 1 Doomsayer and 1 Quartermaster for 2 Piloted Shredders and Sylvanas for Dr.Boom.

Did not feel like I was on the back foot at all all game and beat him through fatigue in the end. Thanks! :D

Worked great!  got my pyro and equality for the early clear and was able to win on my second try.  Thanks!

I am having better luck with this deck than any other Nefarius deck that I've tried.  I haven't defeated him -- yet -- but I made the best progress yet!

Excellent deck. Won on the 2nd try. +1

A big thank you to everyone who's up-voted this deck so far!  I'm glad to hear you're all having success with my deck and find my tech choices to be the more consistent ones tooled for beating this boss as opposed to those in the decks of the sites other contributors.  :D

I'll be sure to add a more thorough and detailed description soon to better help anyone having difficulty.

Nice deck! Got him on the first try. Even after a HUGE misplay on my part that wiped the entire board, I was still able to recover and defeat him.

ughh I can't do this deck I don't have Sylvanas, and Tirion.

Like others have said you don't exactly need them to function but they do certainly increase your win percentage.  Try things like Loatheb and Ragnaros in their place :)

Yea Ragnaros was very usefull to me, thx for the deck

Thanks. Great deck. Third time was a charm.

Agree with the rest here, this deck is better than the others and gets the job done much more consistently. Well done.

After failing about 15 times trying on my own, and then probably another 20 between the current two decks on the front page, I finally beat him with this deck!

Took only 3 tries, great job on the deck!

This is it.

The Druid deck does not have the tools to clear the board well, relies so heavily on luck to get their turn 1-4 curve, or they simply lose.

This deck was well built. Enough heals to survive his random nukes in hand, but with the necessities to control the board.

For the guys wondering, you don't need to build this exact.

You DON'T need Quartermaster or Tirion. You don't need them, and you don't need to luck out to get control of the game in order to win.

I don't have Tirion or the Quartermasters, so I replaced the Quartermasters with simple Piloted Shredders.

The Tirion was replaced with Dr. Boom. If you Don't have Boom, get something else big. He didn't even do work for me except as a 7/7 body. He didn't turn the tide, he didn't win the game.

Have fun, guys.

Had to say, I was tentative because it looked like everyone else was just kissing your ass and slagging off the deck on the front page. However, I tried it and beat Nefarion 4th try. This is the real deal! 

Thanks for this!!!  Got him on the 2nd try.  Agreed far better than the front page deck which failed a good 10 times before I went looking for another deck.

Beat it on the first try using this deck. Great deck, worked very well!

Worked great!!! Much better then the crappy Pally deck on the front page.
