Hearthpwn

Haven't seen it mentioned yet, but I got Warrior on the 2nd try using mainly the enrage package.  Quite a few of the later bosses I faced had a hero power or spells that fed into this and I was able to take The Darkness to fatigue thanks to the candles plus picking up 3 brawls along the way.  

2 classes down.  Mage took a while but eventually I had enough burst, with double Fireball, triple Ragnaros, and Pyroblast.  Druid took no time at all; I had double battlecry, +3 spell damage, and Jades.  My deck was very nearly constructed Jade Druid (triple Aya, double Jade Idol, double Jade Spirit, Kun....oh and double Moonfire double Swipe and Malygos).

 I'm glad to see you not give up after the frustration I've seen from you in other threads :D I'm now 5/9 luckily but for some classes I've tried more than 8 times...

Won all 9 classes with Rod of Roasting and double hp  treasures. (Not joking)

Also Russel the Bard singing the Cobolds and Catacombs song is the best easter egg they have ever done.

Completed Dungeon Master yesterday, all classes completed. Warrior was hardest, for me.

First was shaman vs darkness. The hero power upgrade won me this game.

Rogue, went jade, the rest I went big, another key minion was syvannas. Key weapon, magic spell Creator. Key spells, recruit 3 or silence and destroy. Key upgrades, hero power, their minions cost more, trigger effects doubled. Depending on your deck make up.

1st time was with warlock full blown cthun with 2 additional mana crystals from both passives and lame treasures, final boss was the darkness. 2nd time was with warrior, I got perm stealth so I went with minions that have value from sticking, like frothing berserkers and raging worgens so that one was very easy, final boss was azari. 3rd time was with shaman, I got double battlecries so I went full on jade and I had upgraded hero power so those taunts saved me every game, final boss was beam guy.

Alternative Final Boss Cheese with Any Class: Cloak of Invisibility, Small Backpacks, the cards that add an enemy minion to your Dungeon Deck, add the one minion that is Poisonous to Heroes to your deck, Play it against the Final Boss and pray it lives to go face.

I never got a Treasure Room in any of these runs and I didn't get Quel'Dalas, but they are not needed to win. Gotta admit, Dungeon Runs are very fun!

Warrior -> Weapons, of all things, along with lucky pulls from my Golden Kobold. It was a drag-out fight with The Darkness, but I persevered.

Hunter -> Kept picking the "5-or-more cost 5" treasure until it worked in my favor. Y'Shaarj, Rage Unbound, King Krush, The Lich King, etc; along with the Horn of Cenarius, I just jammed heavies down Azari's throat.

Rogue -> My deck was a bit of a mess: part C'Thun, part Jade, but my bucket offers were all over the place. I only won because Azari literally killed himself: attacked my 14/14 C'Thun with a Wrathguard and died from the self-damage. A Voidlord was up, and I was out of cards in both my hand and deck; my death was inevitable.

Paladin -> Perma-stealth treasure with healing minions. It's hard to lose when Ragnaros, Lightlord cannot be easily killed, and the only person in need of healing is you. I beat The Darkness by abusing Uther of the Ebon Blade's hero power for the alternate win-condition.

Shaman -> Potion of Vitality, twice. With two DK Thralls, I engaged in a lengthy and intense battle to the end with the laser demon; from 200 health, I ended the fight with 27 health and 1 card remaining in my deck.

Druid -> Taunts for days, with a small amount of mana growth and recruit mechanics. Y'Shaarj + Hadronox allowed me to grind out anyone and everyone, including the dragon boss.

Warlock -> A near-perfect highlander setup, with Kazakus, Reno Jackson, Krul the Unshackled, Mal'Ganis and Lord Jaraxxus. I had the super-adapt wand, as well, and adapted a Mistress of Pain eight times in the final fight with the dragon, making her an 8/11 with Poisonous, Divine Shield, and Elusive. The dragon left her alone, and I punished him for it.

Mage -> Hero power, all-day-every-day. Justicar's Ring, Coldarra Drake + a plethora of Inspire minions allowed me to power-slam the opposition, including a 34/34 Kvaldir Raider against the dragon.

Priest -> Another highlander deck, but I added permastealth halfway-though. This allowed me to keep heavy minions like a buffed Lightspawn on the table and bringing the hurt, while I focused the rest of my attention on self-preservation. This was an intense run, though, going to super-fatigue on one occasion and making risky Temporus plays against both Candlebeard and the Chronomancer.

All told, I defeated the dragon three times, Azari twice, the laser demon once, and The Darkness three times.

Rogue with Jades and Deathrattles.

Hunter with Permanent stealth and Best Synergy.

Mage with Double Spell Damage and a Reno Deck.

Priest with Deathrattles, Wax Rager and minions costing no more than 5.

Warlock with Upgraded Hero Power and Wax Rager.

Druid with Ramp and Big Minions.

Shaman with Evolve mechanics.

Warrior with a Pirate only deck and weapons costing 1.

Paladin with an upgraded hero power and lots of win-more buffs.

I have won with 6 classes so below are the type decks i used. One of the biggest problem i see people making is drafting too many early game minions. Early pressure is good in every deck, but plan for the final bosses with 70 health, and broken board clears. Always be a little greedy when drafting, especially with some of the powerful treasures that make it possible to draft heavier decks with less downsides. Full agrro never works. Secondly, look how deck or class can make broken interactions, and exploit them. If you end up drafting a double heal potion, and you have a option to pick a second one, this is usually the correct move because they work well together. If you have a lot of Molten giants, discount them to 5 mana, and tap twice. they become free on turn 4. 

Rouge-This was my easiest win, but i got extremely lucky in my draft. The Exhaust build works amazing, especially with double potion of health. As long as your round Eight isn't against the boss that mills you, its a instant win. 

Druid- I played Quest druid and picked and the treasure that made minions cost 0 for a turn. When you have enough 5 attack minions, you play your spell and finish the quest. 

Warrior- I built a tempo warrior with extra crystals, and the ice wall. This was a probably my luckiest win because the deck wasn't that great, but the build allowed for fast starts and always won you board control.

Mage- Spell power +3 and big spells.

paladin- I got double health and reduce big minions to 5 and weapons to 1. Draft Big dragons, and big weapons. It is powerful in the early game with cheap removal, and allows you to steamroll late game playing two Yeseras a turn.

Hunter- Draft a good mid range deck and get Death stalker Rexar. Win the early board, Draw Death Stalker rexar, win. The wax rager is fantastic in this deck, especially against darkness.

I saw Toast beat Trap Room. Don't play anything, don't use your hero power. Clear his board, and let him get a full tree of secrets. Then let him draw to death. Just keep ending turn. You'll have more cards than him.

I thought I was the "Wacky" deckbuilder. Lol.

So far i've beaten it only with Druid which was stupidly easy. Just go big + ramp and gg. With most of the classes i've got to last boss and still haven't tryed Rogue or Priest. 

There can be more than one ;) ... although admittedly my decks lean more towards the competitive side of things rather than wacky so #feelsbadman.

Well, what started as a wonky Paladin deck with Double Deathrattle and 1-cost weapons, after drawing Val'kyr, turned into this...

Won with mage, final boss vs Azari in a super tight fatigue battle. Then I realized I would have to do that 8 more times with other classes for a lousy card back. No thanks.
