Hearthpwn

Beat it first try using a slightly modified version, because I didn't have some of the cards.

I put in Animated Armor, Prince Malchezzar, Sludge Belcher x2, Emporer Thaurissan, Archthief Rafaam.

Controlled his early board with Frostbolt's, played back to back Mad Scientist's which gave me Ice Block and Mirror Entity, stalled with Sludge Belcher and drew into Kel'Thuzad. Archtheif gave me an artifact of "Give a minion +10/10." Played Alex after he switched to Rag and beat him easily.

thx lot work great ^^

Got it on my first try with this deck.  thank you very much!  

I should add that I took a little time to research how the fight mechanics worked before I started playing.  

I don't have two echoes nor double molten and neither sylv so i did those changes:

-1 [card]Echo of Medivh[/card], -1Mad Scientist , -1 Sylvanas Windrunner, -1 Molten Giant

+2 Animated Armor, +1 Arch-Thief Rafaam, +1 Frost Giant.

Frost giant is included because i don't have the second molten. Animated Armor is awesome to heal 7 damage from Ragnaros hero power when he hits your face. Also pick Rafaam's artifact that gives a minions +10/+10.  Got it at my first try after those changes.

nice ideas. i didnt make  the sub but while making the deck i thought animated armor would work well. good to hear some one tried it out. 

Used a variant of this deck and it worked the very first time. Had a bit of luck, but thanks!

 OMG this deck is a beast. First try won. All you have to do is survive early by using removal(Fireball,frostbolt,etc) then once you get KelThuzad and Echo just use that and more than likely they one will live and you can just create a HUGE board. Then one you have a decent board. Make sure you have iceblock then lower Domo down but not past 20. Then face all your minions. Should be self explanatory from there. 

Thank you for deck. Got it on 6th try. You are right, getting the right cards to stall at the beginning is the key.

I used Echo to get a second KT, end game was simple as pie.  Alex popped out at 16 armor and 30 health.  Three Molten and a 2 KT on board for attack, game over.  Great deck!!

Horrible deck. Nothing but issues.

constructive criticism doesnt seem to get downvoted. only useless comments....like this one :P

giving this deck a go now and it looks really well thought out. i might make a few subs so i have a better chance of having useful cards at start because my first attempt had double moltens and arcane intellect...which ofc i played on turn 3 only to get kt and something else useless.  

EDIT: After the bad rng and the  quick concede my 2nd attempt smashed it with echo of medivh on my KT so i didnt have to worry one bit once they were both in play.

This is was so easy, I even didn`t use Alex and The Emperor, thanks dude :)

I have all of this except the giants, Any optimal replacements?

Thank you, Thank you, thank you. I have been working on that for a while. Great job on the deck.

Got a nice win vs Majordomo/Ragnaros using this deck. Toughest part was surviving the early game 3/3 spam. I actually found the Kel'Thuzad+Sylvanas combo to be the most effective rather than Thaurissan/Alexstrasza.

Also, only had one Echo, but I used a duplicate as an effective substitute.
