First try! Ragnaros is the real star. Without him, the deck does not work as well

2nd try. Tks!

2nd try, Rag and Sylvanas are imprtant guys!

2nd try with this deck. Definitely got lucky with an amazing double Pyromancer though

Replaced x2 Shadow Madness for x2 Mind Control Tech first try

First try victory! There's definitely a luck factor in drawing the important cards when it matters (especially early game so that health doesn't fall too low), but I believe that the key to winning this battle is wise usage of his minions' AoE damage deathrattles (Abomination, Unstable Ghoul) to kill off his own minions.

Mind Control Tech can be amazing here by the way; it's a good replacement for Sylvanas Windrunner. Chances are he'll have 4-5 minions around the time he has 9 or 10 mana crystals. He's capable of dropping 3-4 minions on those turns, "emptying" his hand. Good time to use Holy Nova, Mind Control Tech, or killing his Abominations. I also used Defender of Argus to attack with the Spectrals for damage and/or to suicide them.

I theorize that Power Word: Glory may be used on the Spectrals to help with the healing, because Gothik didn't seem to be actively trying to kill those. However, it requires them to have an attack value above 0, which may be difficult to do reliably, so I don't advise going for it.

Put him down first try! And I totally forgot his play style. Good deck.

worked on my 2nd try, way better than the paladin fatigue version imo

If you havent [card]Ragnaros the Firelord[/card], you can replace to Sludge Belcher

I won on the 2nd try.  nice deck.

it worked for me ... 5 tries

need some luck on drawing cards to beat this boss

this deck almost work, almost, other than the ability to clear spectre and extreme luck on drawing right card... Just like any other deck.

I'm going to test how effective Recombobulator is, seems like it'll be fun. Actually, hell if that doesn't work I'll try full handlock.

I changed one dire wolf for prophet valen and got gothik down on 4th try after having a better start than the first three tries. about 2/3 of the game I had 2 minions from him dealing 1 damage each to me but with velen up several rounds it was no problem

Doesn't work for me, I am usually in losing position by turn 5 :(

Got it on first run! Amazing deck man

After trying several druid and paladin decks, this one did it first try. Sniperino Rag MVP :D Didn't even have to mill him.

Ended up with a one-shot thanks to this deck. Prior to this I tried half a dozen home brewed decks trying to find the right one. This one worked the magic. The only differences between my version and the posted version was I didn't use Sylvanas (don't have), used Mind Control Tech instead, and I took away one Shadow Madness for one Shadow Word: Pain.

Solid deck.

I had to make a few mods for cards I don't have, but after failing with 7 other decks over 2 dozen times, I one shot with this.

A tweaked version of this decklist got me there (-1 Silence, -1 Shadow Madness, -1 Sylvanas, +1 Shadow Word: Pain, +1 Earthen Ring Farseer, +1 Azure Drake), but I wonder if Defender of Argus would be even better than Deathlord (which seems to be only a minor nuisance for Gothik when he's churning out an endless stream of minions).
