Hearthpwn

Tnx, win with 1st try!

Garbage RNG deck, not enough time in the leap hear to waste any more ties on it.

These decks don't have enough of the assets of newer cards.  I struggled to get the right combo... Switched to a boss build Mill Rogue deck and took him out the first time. Sap + Pit Snake + Coldlight Oracle

Wow thank you, got it at my first try, and i had a lot of missing cards.

Been having a tough time with finding something consistent against Thaddius. Pally seems the best so far, won with this deck on first attempt. Put in Ancient Healbot instead of second Lay on Hands.

I tried all the recommended decks from the guide with no success. I am now at my at least 20-30th try in total. This deck however works amazingly well!

I used a slightly changed version with Stalagg and Feugen since I am missing a bunch of cards, including Tirion

My tip: Use equality on turn 2 if you have it, this reduces incoming damage to 2. Try to open up with a egg on turn 2, or if needed, put a second equality which reduces total damage from both to minimal. 

For me, I used equality on turn 2, drew into a pyro and combo'd pyro with Humility to get rid of Stalagg, Feugen and the Stoneskin gargoyle at once (since all were on 1 health)

Thank you for posting this deck as I wanted to quickly get Death's Bite and Thaddius was giving me a bit of trouble.

I beat Normal Thaddius on my first try and Heroic Thaddius on my 2nd attempt using a slightly modified virgin (sic) of this deck. I did not have Lay Hands x2 or Tirion, so I replaced them with an extra Argent Commander/Elven Archer, and a Sunwalker. I did not find the elven archer to be especially useful, but the other two cards were valuable draws.

Well met!

Thank you for this build, I tried out 3-4 other decks that were all more highly rated on hearthpwn or featured in the strat guide and died to RNG each time, even when I'd mulligan in my favor or just concede for a better starting hand.  This deck worked first try with a subpar starting hand and was fun to play and counter with.  Thank you for posting!

Off all the decs i have tried on this site against nax heroic. This is the one that counters the hardest. It is also the deck i had most fun winning against a heroic boss with. In short an amazing deck and lots of fun to crush Thaddius with!

pass it at third try ! nice deck !

This deck sucks. You got lucky if you beat him first try with this deck, I've done the same strategies explained by all of your comments, and MY Thaddius counters it with spells. I have beat this boss with my own deck because this one isn't good at all.

Didn't have Tirion so used Gruul instead. Great resource since he can take damage and always gain some back. Also only had 1 Aldor and Avenging Wrath, but the key here was Feugen and Stalagg. Given that killing his copies proc yours as well, you can get out multiple Thaddius-es (Thaddii?)

Very satisfying. 

Edit: I was using XanderinV's version of the deck, not the OP's. 

I actually one shot Thaddius with this deck. All the other bosses took me multiple attempts except this one. Made a video on it too: 

Excellent deck, made this the easiest naxx boss.

For those asking how to kill the initial adds, you only have to use any of the many cards that turn their attack to 1, the next round when they flip you can kill them with 1 dmg from cards like the archer, consecrate, the taunt guy that does 1 dmg to the board when he dies or even kill them with a token.  There might be some bad rng out there for some of you but you have to make sure to mulligan correctly to have a better chance.  Equalities or humilities are prob the best.  2 equalities and they turn into 1 1s.  The taunt guy would be the next ideal card but you can use the archers or anything really.  The egg is nice since it instantly turns into an 4 4.  Hope that helps.  Pray to your rng gods. 

I didn't have a Lay on Hands or a Tirion so I replaced them with a Ragnaros (which did most my dmg at the end) and an Alexstrasza which I used to save myself when I was at about 2 hps.  I think I 2 shotted it.  This is a fun fight.  Lots to think about.

Would love a video of these so called 1st try kills, with time stamps as well because I'm calling bullshit to every single on of these. Even with equality elven archer unstable ghoul dream opener you still get shit on by the shaman cards plus ridiculous dmg flips

Even with dream opener you are down to 15ish by 2nd turn, repentance doesnt work on first creatures btw its a waste of cards

Ok noble sac into equality into elven archer into humility into truesilver champ into loss lol. He had almost 0 dmg on board when I ran out of steam. Then he went into back to back belchers and you lose from there. There is no way this is a one try deck, not only do you have to have perfect luck on your side but you have to have perfect bad luck out of the computer

I agree. This deck has to be lucky to win. You HAVE to top deck like a pro for it to work, which isn't a good deck.

Got it on the second try.

5th try, death by turn 5 whatever you try... this deck is serious?

8 th try got fordring, result i die,  he just killed it with forked lightnings and shit

9th try getting egg and 2 bubbles, hsould do, double lighting bolt kills the 4/4, 

dit :got there after try 20 where everything went perfect and wrong for him
