All decks i finish @ first try. good decks

If you're going after Barron Geddon or Majordomo I highly recommend the priest decks.  As long as you don't get a bad draw to start you should have them within 2-3 games tops.

If you want a fun challenge, try killing Garr with Nat Pagle

 

BALLER PAGLE FTW

1st try Circle of Healing is a must.

Here's the Mill deck I used to beat Majordomo. It was fun seeing Rag take fatigue damage :)

Experienced a bug (or at least I think it was a bug) wherein rag in the heroic fight would not use his hero power. 

I dont know why rogue mill decks are not listed for geddon and domo.  THey are the best way to get past those bosses.  And a priest with mass dispels is best for garr.

*I dont have as many GvG cards as PhoenixMP but he is the only one that posted a mill deck to easily beat domo and geddon.

Sideboard : Antikill bot, Lorewalker Cho, Emperor Tharussian, Big Game hunter, king mukla.

I really like the Garr one

Just watch Kripparian VODs, his decks are better than any here, he 1 shotted all the bosses, i 1 shotted 2/3 with his decks, they dont call him SKILLARIAN for nothing :P

These Heroics are substantially harder than the previous wing tbh.

I assume that they make the first wing easy so that people buy the second wing. damn blizzard, why can't you be less power-hungry

It's just so funny to me that in casual, rank or arena I hate battling priests or even playing priests in any of these modes but in adventure they seem to be the best to use especially the harder bosses.  

I beat Garr with this Priest deck. It's pretty cheap. That was also a list that i use in ladder.

For Majordomo i use this Mage deck. All you have to do is wait until you have Antonidas and 3-4 Sorcer's Apprentice, and then spam Fireball to Majordomo face.

Both the time i win at the first try

For Geddon i used the Priest deck of Tehstool.

Helped a lot thanks!

This anti-Majordomo deck is very effective, one shotted him, after several tries with priest. 

Majordomo used a lot of his removal on the Azure Drake and Thaurissan, so I cought him off-guard I guess, this was the board that i spawned Rag with and the Rag kill, it took exactly 10 mana, for 10 Fireballs. Guess with Thalanos, could have been more mana efficient, but it was fun casting 10 fireballs... when could i ever do that? Rag luckily hit my face for the double 8 damage, instead of Antonidas.

[edit] sorry about just link to the image, tried to insert it, but failed.

0_o this best combo ...but how do play ??

Both Baron Geddon Heroics and Garr Heroics downed with Priest deck :) Now its finally time to rest before the next release 

For the heroic majordomo fight, i accidentally left him at 4 health and he summoned a bunch of molten giants. Was about to concede but decided to push on and give it a try.

I successfully brought the fight to ragnaros phase the next turn and then defeated him without the molten giants ever doing anything. The molten giants never attacked the whole fight, not even once.

Anyone else experienced this? My guess is that maybe ragnaros can't control the units that majordomo summoned, but not really sure on this.
