This worked perfectly for me.  I swapped Mulch and Tree of Life for 2x Primordial Drake and it worked flawlessly

Guaranteed easy win.

Keep yourself survive till you have Riven,Feugen,Stalagg,2 freeze spells(except blizzard) and wailing soul.

Turn 1: One of S or F or Riven, then freeze it.

Turn 2: Put the rest of the three, freeze Riven only.

Turn 3: wailing soul and win.

Sapphiron will always keep a freeze spell in hand so wailing soul is absolutely necessary.

Did it in the 1st try! Thanks!

1 part strategy, 9 part luck of the draw. I know the same can be said about any deck, but much more so with this one.

Finally I beat it. First attempt failed because I don't get how it work, so funny anyway :) Thanks

This is clear instruction how to play the deck :) Thanks

I found him to be one of the hardest in Heroic Naxx, but I was able to beat him pretty easily with this deck that I made.

Thank you, that is THE way to beat him: I did not thought of killing him with fatigue! Excellent strategy, got him easy with this deck!

Thank you, the only deck who man can find here what really function from the first time.

All other decks need so damn luck. 

Like this from Fm_the_Feeble. 6 cards for the combo, after 5 times i give it up cause one of the combopieces is allways the last one.

No friends, use this one, thats the real thing.

Peace

Only Sapphiron was left undone for me from the previous year (when I tried to get them all done during the summer) since i was unable to do it after countless tries and some missing mage cards. Just got blizzard and searched for a guide and this was so good that even without it (blizzard) I would still have done it on the 1st try, like I just did. Thanks!!

I used the amaz freeze mage but i replaced 1 arcane intellect for Reno Jackson and it worked much much better because I always died in the fatigue game without it.

We used a Paladin combo deck for Sapph that worked pretty well.  If you need help, here's the guide we made. :)

I killed him second try with this.  Just control the board until the end and make sure he draws more cards than you.

I did it with mage without any of the epic cards, just Blizzard. Give it a shot, follow the guide.

I'm trying this with druid.  Since many of his minions cannot be targeted for destruction, I am trying Abomination, Unstable Ghoul, Starfall, Swipe, etc. for AoE.  But he drops so many friggin' minions!  I can wipe the board 2 or 3 times and it barely slows him down.

The secret hunter deck is very good against this dragon
