Edit: Added a gameplay video, up against a tryhard Secret Paladin and trying to survive as long as I could! The worst thing about the Warlock class for this challenge is the Hero Power. It damages your hero to draw a useless card. All other classes Hero Powers at least have *some* merit!
Well I guess that this deck just stalls the game. Taking Paladin with some Kings and Blessings will probably make yourself kill even faster lol (including a bunch of heals to like you know heal your opponent xD) and it has no synergy with anything except of minions which is I mean not a combo or anything else
I did my worst. Lifetap can kill yourself, but on the upside (or downside) it's giving you more minions. At least, some of the Cards are truly dead. Never playable, so that will delay the zooish character of the deck...
Was going to make a Warlock or Priest but I saw that other users already did and wanted to do something different. The only damage output you'd get from playing this deck is your hero power and maybe some spells from Lorewalker Cho. Other than that it's full of useless minions, pointless mana gains and card draws. Enjoy taking it to Rank 26 ;)
