Cards to AddĪbomination, (more board clear), Zombie Chow (nice potential heal), Deathlord (get some stronger minions out early). Ideally you want to start with two cards to help you control the board ( Unstable Ghoul for example). One thing to keep in mind is if your Berserkers die off quickly you may have trouble killing the boss without him entering fatigue (which at the rate he draws cards is probably very possible). If you can play a Tentacle into a Mirror Image, then a Berserker you’ll both clear the board for your Berserker and massively buff it. Gurubashi Berserker combined with Unstable Ghoul or Tentacle of N'Zoth are an amazing combo. Just don’t play too passively – remember that with all 6 of these commons you have several ways to remove minions from the board, and every extra card you add on top of that will only increase your chances. If you do end up using this deck, I would recommend saving Explosive Sheep for Flamewaker, as two sheep do 4 damage to the board. If it ends up being a Counterspell (which is worst case scenario in this example), you’ve still just dealt 2 damage to everything on the board. If it’s a Duplicate and you ping the newly created Tentacle, the boss will then have multiple Tentacles put into his hand.

If it’s a Mirror Image, there’s now 3 potential aoe damage on the board. For example, say you play a Tentacle of N'Zoth.

So this boss has 3 secrets, all of which are actually fairly easy to play around ( Mirror Image, Duplicate, and Counterspell), and can be used to your advantage. Finding cheap cards that could be used to take advantage of it was a lot of fun. Having said that, I love the boss ability.

Unfortunately I felt that this boss wasn’t killable on heroic with a free to play deck, so I added a few commons to help with clearing the board which made it a lot easier. Tommy J generously allowed us to host his decks and guides using (mostly) Basic cards to take down One Night in Karazhan Heroic bosses. Be sure to check out his YouTube Channel.
