Summary

This deck is primarily for fun and isn't expected to be very competitive, but it does provide a few ways to have powerful swing turns, create snowballing board states, or burst down your opponent. The main idea of the deck is to use Defend the Dwarven District and its rewards, together with hero power synergy cards, to generate value.

The Quest

To understand this deck, you first have to understand the Defend the Dwarven District questline. Questlines are a new mechanic in United in Stormwind; they function similar to quests from previous expansions, but they have multiple steps, each with a reward. Here are the pieces of this particular questline:

As you can see, completing the questline requires dealing damage with 6 spells in total, and once you are done, your hero power will cost no mana, be able to target minions, and (after you play Tavish, Master Marksman) refresh whenever you play a spell.

The Mulligan

Defend the Dwarven District will always show up in your opening hand, and you will want to keep it there. Even if you are playing against an aggro deck, the reward for the first part of the questline is useful enough that it is worth pursuing. Aside from that:

Keep:

• Any spells that deal damage and cost 3 or less so that you can make progress on the quest as quickly as possible. The only exception to this is Explosive Trap, because it is better to pull it from the next card...
• Mad Scientist
• Secret Plan, because it can be used to discover a secret that deals damage or is otherwise useful early in the current matchup
• Entrapped Sorceress

Don't keep:

• Secrets
• Cards that cost 4 or more, except perhaps Reno Jackson if you are expecting an aggro matchup.
• Inspire cards. These are meant for the late game, even if they are cheap like Silver Hand Regent

The Early Game

Avoid the temptation to always play Defend the Dwarven District on turn one. It may make more sense to play Secret Plan or Tracking, or even coin out a Mad Scientist, depending on the situation. Certainly play the questline if you have nothing better to do, or if you know you will want to play a damaging spell on your next turn, but if you have Secret Plan in hand and you can tell you won't be playing any damaging spells for a few turns, it is better to lead with Secret Plan. The same goes for Tracking if you think you know what you are up against and you can tell you won't be spending all of your mana on damaging spells on turn 2.

That said, the goal in the early game is to use your damaging spells to make progress on the questline quickly while clearing your opponent's minions. Keep in mind that this is a value/control deck. Unless you don't think your opponent is going to be playing any minions for quite some time, don't throw your spells at your opponent's face just to complete the quest; you want to be using your spells to kill your opponent's minions.

The Mid Game

By turn 3 or 4, you should be able to target your opponent's minions with your hero power. Use that and your other resources to control the board while finishing the questline. Avoid playing your inspire cards until you can get maximum value out of them in the late game, unless you are in an aggro matchup and you have to use something like Tournament Medic to heal up a bit.

The Late Game & Win Conditions

After completing the questline and playing Tavish, Master Marksman, it's time to take advantage of that hero power! Hopefully you have been able to keep control of the board, because this mainly works by snowballing a board of your own. Silver Hand Regent or Kodorider can be combined with Mukla's Champion to create a board that generates minions and buffs them up every time you use your hero power, which you can now do for free multiple times a turn. Keep in mind that inspire effects will trigger in the order the minions were summoned, so play Silver Hand Regent before Mukla's Champion. If you can stick a board like that or even just a Kvaldir Raider, Nexus-Champion Saraad becomes more than the value machine he is on his own.

Aside from the inspire cards, games can be closed out with a few of the singleton cards in the deck, including Dinotamer Brann, Dragonqueen Alexstrasza, or Zephrys the Great.

Combos

This deck has a few noteworthy combos:

• Devouring Swarm and Stitched Tracker can be used to get multiple copies of some of the powerful minions in the deck, such as Mad Scientist, Zephrys the Great, Reno Jackson, Dragonqueen Alexstrasza, or Dinotamer Brann. Even Rustrot Viper might be one you want to play twice vs. a deck like Kingsbane Rogue. When you play Devouring Swarm, minions will attack in the order they were summoned, and will stop attacking when the target minion is dead, so give careful thought to the order you play your minions. If you use Stitched Tracker to get a second Mukla's Champion, the two copies will buff each other; this isn't particularly powerful, but it is good fun.
• Kill Command has synergy with the Hyena summoned by Wound Prey, the Wolf summoned by Flanking Strike, the Wyvern summoned by Unleash the Beast, King Krush summoned by Dinotamer Brann, Rustrot Viper, and Mukla's Champion.
• If you can build a wide board, Zephrys the Great can give you lethal with Bloodlust. If you can stick a King Krush, Dragonqueen Alexstrasza or a big Kvaldir Raider, Zephrys can give you Windfury for lethal.

Substitutions

If you are missing any of the cards in this deck, or just want to make some adjustments, there are a few good substitutions:

• Barak Kodobane is useful for tutoring your damaging spells for quicker questline completion in the mid game.
• Bola Shot is a fine damaging spell.
• Wandmaker, Mystery Winner, Resizing Pouch, and Venomous Scorpid can be used to generate more damaging spells.
• Manafeeder Panthara has great synergy with the 0-cost hero power.
