This deck's main idea is to use low drop taunts to protect yourself from Gothik's minions, clear the board with aoe and make Gothik draw so many cards that he will not be able to handle them. It took me some tries and card changes before being able to defeat him but eventually I was successful.

I have been trying adding big tanks but they are almost useless since Gothik won't give you time to summon them, he will smash your face with an army within 5 turns or so. That's why Dancing Swords, Unstable Ghouls and Deathlords are there, they will give you an early board control while you wait for him to build an army so you can destroy it with your aoes. However, after doing that you will find your board full of unwanted minions that will damage you every turn: get rid of them by using Poison Seeds, Doomsayer, Savage Roar (attacking your enemy minions) or even comboing Abomination's and Unstable Ghouls' death (it may seem really unlikely to happen but I did it so many times) in order to kill them through their effects. Use aoe wisely and hold on as much as you can. Going aggro is pretty much useless: you NEED to lower his board control, nothing else.

If you manage to survive about 10 turns... your enemy will be almost out of cards on his deck and you should be able to finish his last minions. I hope this deck will be helpful and lead you to the victory!!
