Warning: win condition depends 100% on RNG! Lots of pain awaits you. For those who do not know, after pressing menu button there is [restart] button, you can use for faster attempts.

Welcome masochists, who are trying to win this heroic boss. Never made a guide here before, but since this boss is probably the hardest one there is right now and there is so little ways to defeat him, i decided i would share my experience. This is the exact copy of the deck i used to defeat this pain in the arse boss.

Edit: You can replace the cards in this deck, just don't use Counterspell, since it can prevent boss from summoning the minion you need. And don't worry about Potion of Polymorph, it won't stand in your way of summoning what we need. The rest spells are there to stall the game, freezing his minions, getting armor/immune, copy/polyporph to deal with his minions. /Edit.

Edit2: Tried decks, before i won, with Kel'Thuzad, they seem to patch it. As soon as you draw it, you can only hope for Kel to survive a turn or two. Seems pretty useless to me. /Edit2.

After trying many decks, i found one similar to this, which got me pretty close to defeating him. Similar deck includes Doomsayer which i do not own and another one that i saw includes Deathwing. I think it would be a lot easier having one of those, but since i didn't, i had to play a LOT, for the stars to align. Took me many hours, but eventually it's done. And now to the part where i talk about how and why:

You need to force the boss to copy your Majordomo Executus, to do that we need as less minions in the deck as possible, having only him and/or Doomsayer  or Deathwing we get 100% and 50% chance for him to summon it respectively. If you draw Majordomo Executus into your hand, concede, because the boss can only copy minions that are in your deck and not your hand.

The trick: he plays a spell and summons Majordomo Executus, you kill it with Flame Lance in the best scenario or use Vaporize and hope he hits you with Majordomo Executus, which happened around 50% of the time, he turns into Ragnaros the Firelord, losing all his armor and HP drops to 8. Now his hero power costs 2 mana and deals 8 damage to a random enemy target. Now you must know that since his hero power is replaced, you both start getting mana crystals and cards cost as they usually do.

Win condition: Having Mirror Image, will save you for a turn or two, from his minions and/or hero power and costs only 1 mana. You want to use your hero power as much as possible, because your win condition depends on Fireball or *Ice Lance*, *Frostbolt*. Remember, normal cost for all the cards!

If you get unlucky, he may play his spell [destroy a minion and gain 10 armor] in Ragnaros the Firelord form, then you're screwed.

I won, when he had 2 minions, used Mirror Image on Turn1, Hero power Turn2, Hero power Turn 3 and finished him off with Fireball on Turn4.

Considering how all this works, any class can defeat him, all you need to do is have 28-29 spells in your deck, kill Majordomo Executus and then have cheap spells that could deal 8 damage to finish him off.

So my thought is that playing druid, using Naturalize on Majordomo Executus and then something like *Innervate*, *Moonfire*, *Claw*, *Living Roots*, *Wrath*, *Feral Rage* + hero power, may finish him off. If he does not have a lot of dmg from his minions, also Living Roots can be used to summon sapplings to avoid his hero power. Well, this is just my speculation.

Edit3: Added *stars* to the cards, for more readability.

Edit4: I gave it a second thought. Having Deathwing and drawing it from the start, would make this quest super easy, just wait for that Majordomo Executus to be copied, drop your OP dragon and if he does not have destroy spell, you won. Best and easiest condition ever.

Have fun.
