Gothik the Harvester in Heroic Mode - so far the best Blizzard's creation in terms of AI challenges. His tempo is huge, his "give opponents tokens" mechanic is interesting and powerful, his combos are solid, he easily counters aggro with Abominations and easily deals with big minions with Corruptions. With him I had to do more tries, more deck changes and more thought put in, than anyone else. So I went with only option I've come up with - Fatigue That Bastard.

First thing we have to deal with is making use of those tokens or preventing them from happening. I had little luck with Shaman and his Flametongue Totem (DAMN YOU Crazed Alchemist), so I turned to Priest and Inner Fires to take the first role, which has much more sustain and useful cards for that matter.Shadow Madness and Mass Dispel are cards for preventing the tokens, but I'm still in huge doubt about both due to their huge cost, anyway, they often were useful so here they are in kinda-final variant of the deck.

What about common token-enabling cards for that matter, I advise ignoring Dire Wolf Alpha and getting max amount of Sunfury Protector and Defender of Argus (I have just one Argus in my collection and even that I crafted of little frustration to beat this boss).

Priest's removals via Shadow Words and Holy Fire are a go-go. Mulligan for AOE-removal with Auchenai Soulpriest and Circle of Healing. Play this combo only for great value or you will lose.

Dancing Swords happen to be awesome, as they give huge tempo, trade with almost everything and survive, kill Abomination by themselves and give Gothik more cards, which absolutely doesn't matter. Nerubian Eggs will be enabled anyway with lots of Abominations, so that's solid as well. Our own Abomination has to do very-very well, as we long for AOE, while Holy Nova costs a lot and does a little, and Auchenai Circle combo is yet to be drawn (consider having 2 of these cards).

The one card I didn't try out (because I challenged myself not to craft anything, but failed anyway) is Mind Control Tech. If you have those guys in collection, try toss them in instead of Northshire Clerics or Earthen Ring Farseer and tell me how do you feel about them in comment section, please.

Standalone taunt cards are pretty essential, but you may pick any of them. Oh, and Lightwell. Actually, it saves a lot of hitpoints for our precious face, if not Crazed Alchemist'ed and being drawn in late-game, actually kinda won me the game. But also to be considered to get replaced with Abomination or Sludge Belcher, for example

If you have any questions/suggestions/angry reviews, please, write them down in the comments. GLHF!
