Nice! He has a habbit of going face a lot, so if you get down chromaggus he wont kill it. Holy nova double drakes and eventually kelthuzad is how i won.

1st try! Thanks!

Good deck, beat him after a few tries :) the important thing is to try for board control from the very start, even if that means playing an ooze on turn two!

No you should really save the ooze for onyxia.. That's the whole point.

Nice deck, did heroic in 3 tries

Yeah i also noticed, haha :p

yo man thanks for the deck one of the most fun games i ever had in a fight vs a boss i stalled the game until i got the chance to get him to the 3rd part the second neferian and then he fatigued to death lol btw chromagus was my last card FeelsBadMan but i stole his with mind control

This looked really good and I thought I was finally going to be able to deal with this boss after two weeks of trying, but alas, it's ended like all the other decks I've tried.  Played 20 times with it, lost each time.  Never once made it past the Onyxia stage of the fight.  Even when I have the suggested "perfect" draw, he just murders the dragon turn one with soulfire and then overwhelms the board.  I can't ever catch up.

I have fought this boss, no lie, about 200 times at this point and am still no closer to beating him.  I've watched videos, played a dozen or so different decks that promise a win, and nothing.  The fights never play out the way the videos do and none of the instructions for the various decks lead me to victory.  I'm pretty much at a boiling point with this fight.  I've never seen a difficulty spike like this in any game I've ever played.

All this isn't to say that the deck doesn't work.  I'm sure it does.  Plenty of people in the comments say it does, and I have no doubt that it works for them, but there seems to be no deck on earth that I can personally win this fight with, and the frustration is starting to get to me.

Haven't won yet, mostly because of constant bad draws and my lack of skill, but this deck has been consistently getting me closer than anything else I've tried so far.

I'm on NA, thanks for the offer though!

Beat it first try, thanks!

still working.... 3rd tried ;)     13/10/15

Thank you, I was able to finally beat Nefarian with this deck on the first try :)

This deck also wins versus facehunter on Rank13 :D

Thank you BRO o/ , works very well !!!

Beat him the 2nd try! Thanks brother!

five tries and I can't even get to the second phase.

*double checks to see if there are even deathlords in my deck*

yeah I really wish I'd seen one ever!

1 loss and 1 bad mulligan but won on the third try. Great deck, thanks!

FYI if anyone else is just trying the normal bosses, the Twilight Whelp cards drop from the Priest class challenge. Didn't seem difficult, beat it on the first try.

this helped me tremendously thank you for taking the time to put it together
