This is my version of DK OTK Paladin. Currently ranking from 5 to legend with 80% win rate so far. The deck is very solid with incredibly fast draw, lot's of healing and board clears and an almost uncounterable OTK finish from the paladin death knights Uther of the Ebon Blade hero power The Four Horsemen.
The basic goal is to cycle fast, survive and assemble your combo using Zola the Gorgon and Ancient Brewmaster to return 3 of the death knight hero power minions Darion Mograine, Deathlord Nazgrim, Inquisitor Whitemane, and Thoras Trollbane to your hand. Then you can play 3 from your hand + hero power in 1 turn to win the game.
Keep in mind the 4 horsemen need to be unique so don't pick the same one up twice. That will not work.
Soup Vendor also works with the death Knight weapon Grave Vengeance hits and Truesilver Champion hits while Crystalsmith Kangor is on the board. It also is an easy fit for our Call to Arms. Also a dream scenario of T4 Truesilver Champion into T5 Call to Arms which pulls Crystalsmith Kangor and 2 x Soup Vendor giving your second Truesilver Champion hit 4 heal to draw 2 cards from the Soup Vendor's.
Time Out! is the mvp of the deck. Amazing for stalling and buying time while trying to assemble your combo pieces or when you don't have a clear and need to avoid a lot of damage. It can also be used with weapons on the turn you play it to take no damage from the weapon hit. Can be very nice for topping up your health while using Grave Vengeance to kill a high damage enemy minion while you take no damage especially combined with Crystalsmith Kangor.
Dragonmaw Scorcher is another way to clear the board with Equality or Shrink Ray. A much needed addition especially when Call to Arms pulls your Wild Pyromancer. Can be great on it's own too to clear up baku paladins guys or any low minions.
A few tips.
The hero power summons randomly but can only summon horsemen that are not already on the board. It can however summon a horseman you already picked up if it's not on the board. Sometimes you will get unlucky and summon the same 1 multiple times in a row. A tip for copying the horsemen is if you have zola and brewmaster, and don't need the excess mana to do something else, you can copy the horseman with zola and pick the zola back up with the brewmaster. This leaves a horseman on board making the next hero power on the following turn summon a different horseman if your opponent does not remove it. It also gives you a cheaper way of copying a horseman in the future. This can be important. Let's say you want to shrink ray to neutralise an enemy board. You can now still hero power and copy with Zola if you hit a horseman you don't have in your hand.
Don't be afraid to burn combo cards like brewmaster and zola vs hyper aggressive decks like zoolock, odd paladin, odd rogue, etc. You can win the game without them and if they are your best tempo play then use them. You can do some funky stuff like zola the kangor to get a second kangor, play it and then the healing is doubled again. It does stack. Once these decks exhaust resources you can kill them with your weapons and hero power minions. You will find odd paladin, zoolock and odd rogue will self damage themselves for a fair amount of hp anyway. Uther weapon + consecrations is usually enough to kill them if you get the opportunity to start going face.
This is a quick write up. I'll add more if there's interest. Let me know what you think and how you get on. 3 other cards worth considering are Blackwald Pixie, High Priest Thekal and Shirvallah, the Tiger. I dont have Shirvallah, the Tiger yet to test and Im not sure what to cut for 1 Blackwald Pixie yet. Pixie allows us to OTK with only 2 of the death knight hero power minions if we have the coin. It also allows us to summon a second minion to copy with zola if you already have the first minion. High Priest Thekal is also worth considering. I don't have it to test yet but it would improve the consistency and value of our heals and draws that rely on heals vs decks that don't damage us much like other otk's.
-edit- Cut 1 Dragonmaw Scorcher and added 1 Gluttonous Ooze. The only way druid otk's can easily kill you is with weapon tempo combo. Kingsbane rogue is also making a return to the meta. Also great vs other weapon classes and lich king weapons. You draw so fast you will almost always have it when needed. Also just a 3 drop to throw on curve vs non weapon aggro.
