Hearthpwn

basically just like the meta: rng/luck from the start or lose.

Only done Hunter so far, Controlled the board with secrets til turn 7, struggled through phase 2, then played DK and kept digging for Lifesteal Zombeasts to stay alive while burning him down. I used the Barnes + Sneed's combo, and got lucky with Sylvanas, but apart from that, just ground it down with Zombeasts, with a few lucky ones, including

Bloodworm + Dispatch Kodo

Bloodworm + Tundra Rhino

Dispatch Kodo + Stubborn Gastropod

Deck list is 

Just got started a few hours ago; I'm left with hunter, rogue and paladin. 

So what I did:

Mage: played some sort of midrange/value mage with lich jaina and medivh as finishers, cheated with kabal lackey and counterspell.

Hunter:  used beasts and molten giants rushed him down (rip 400 dust on molten giant XD) - 2 tries with this deck.

Paladin:  control paladin with kelthudzad cheat, (copied from HPWN not my idea) - 1 try with the deck posted on HPWN.

Warlock: Used my wild demon renolock, didn't tweak it at all, got it first try. (first class aswell)

Rogue: took out the advice of going full aggro pirates one eyed cheat and ships cannon  did some work here. - 2 tries

Priest: Big Priest, took a few attempts to high roll also crafted 2 statues (800 dust) but they are in big priest anyway and I wanted them so it's ok. 5-6 tries

Warrior: wow this one was hard, put togheter a control warrior, then I kinda cheesed him with kelthudzad and anti magic shell (that I got from my lich king) was the hardest for me, dunno how a budget deck can beat him.. thing you have to have at least kelthudzad and N'zoth. 5-6 tries

Druid: easy unchanged ladder jade druid wasn't even a challenge. sad. 

Shaman: took me the most tries (warrior took me the most time ) I tried a token deck at first but then switched to murlocs. about 10 tries I think? I just conceded a lot.

 Can't see how he can be defeated by certain classes without specific cards though..

So what I did, took me about 6-7 hours, but nice hero

Mage: molten giants with duplicate and sunfury

Hunter:  molten giants (reset until 2 giants)

Paladin:  Murloc pala with insane curve pretty good xD

Warlock: Used my wild renolock

Rogue: pirate midrange, started doing damage after doomsayer on turn 7.

Priest: silence priest took a few tries and finally killed him

Warrior: patron and frothing berserker, old patron still fine 

Druid: second try with jade druid, first time playing it xD

Shaman: evolve shaman with bloodlust is fine for killing him before turn 7.

Done

1. Mage: Exodia

2. Druid: Jade

3. Hunter: Hyena/Fledgling (Turn 6 ko)

4. Shaman: Quest (Turn 6 ko)

5. Priest: Divine Spirit/Inner Fire (Turn 6 ko)

6. Warlock: N'Zoth Krul Renolock

7. Paladin: Murloc (Turn 6 ko)

8. Rogue: Pirates (Turn 6 ko)

9. Warrior: Patron, N'Zoth, and Dead Man's Hand/Codlight fatigue strategies all mixed together.

I can't tell the details anymore, but I'm finished ...

Mh ... haven't been able to beat him with a single class so far. Let's explore the boundaries of my patience a little further.

Edit: Got super lucky with Evolve Shaman and won. That shall be all for today, though. xD

hardest for me was paladin and hunter, everything else was easy

Warlock: Used reno demonlock. I had to use malganis to nullify the damage from the 3rd heropower (Took 2 tries)

Mage: At least 100 tries. Had to draw so specifically to get double molten with kabal lackey plus mana bind.

Shaman: Just used a Lust and Evolve Shaman deck (Took 3 tries around)

Warrior: Abused the frostmourne phase to set up a sudden genesis with keltuzad combo. Filled the board with kelthuzads and smorc'd (Took 10 tries since I kept fucking up the amount of cards in hand)

Paladin: Used a aggro murloc paladin deck and subbed the 6+ drops with more buffs (Took a few tries to get the right hand)

Rogue: Just used a nzoth deck with strong deathrattles like belcher and sylvannas. Also incorporated the dk (not needed) and healbots(very needed)

Hunter: Surprising I went the molten giant route. Basically put a lot of minions to put me at low health to play moltens early and used stitched tracker to get them out. Then used the hunter dk with 2 fledgings to push lethal after frostmourne stage.

Priest: Used the quest for healt gain and nzoth to push damage at the end

Druid: Jade druid

After a million hunter games I finally pulled Barnes on 4. 

. . . there must always be . . . a cheesy boss fight . . .

4 hrs. Done with all 9.

Quote from JustGTFO >>

Mage: after some failed attempts, I made a DK Reno deck that finally worked.
Warlock: Krul Renolock made it fairly easy.
Priest: just a regular Penguin OTK Priest.
Druid: just a regular Jade Druid.
Rogue: made a Zoo Rogue that somehow worked.
Shaman: just a regular Token/Evolve/Bloodlust Shaman.
Hunter: needed god draw to shut down his turn 6 and 7 with Doomsayer into Medivh and double Call of the Wild.
Warrior: made a very weird Zoo Warrior with Cobalt Scalebane and Alley Armorsmith to stack some serious armor and kill the LK with a board of 10+ atk minions. Turns out, 11/7 Alley Armorsmith is preeeeeetty good.
Paladin: Anyfin Can Happen.

Finally finished :D

Took me about 4 Hours.

Priest 5 Trys, Mage 2, Warlock 1, Rouge 1, Shami 1, Warrior 3, Druid 2, Hunter 15 and Paladin 32.

I can't win with paladin and hunter... :(

Completed all of them, but all I can say is that the Lich King has no answer for the Murlocs. They are superior. ^^

Wow 17% of people on this poll have him haha more than I expected. Then again players that hang out on here are probably dedicated players xD

Struggling with warlock and then I'll have him. 

My biggest problem seems to be not having the cards that got sent to wild, like Mal'ganis.

If anyone has any suggestions, I'd really appreciate it.

I've completed 6 of 9.  Still need to finish Paladin, Warrior and Hunter.  Been struggling with Warrior.

Finally i was able to beat the Lich King with alo the classes, at one moment i gave up but then Murlocs saved me.
