This guide contains detailed Strategy, Mulligan, and deck-building information to help you play Questline Warlock in The Deadmines expansion meta.

Questline Warlock is a unique deck that utilises self-damaging effects to fully complete The Demon Seed Questline. Upon using the Questline reward, the deck is then able to reflect its self-damaging effects towards opponents in order to quickly burn down their Health.

Questline Warlock Deck Mulligan Guide

As with playing most Questline decks, it is important to look for key cards in your opening hand to speed up your Questline progression.

  • General Mulligan (keep regardless of what your opponent is playing)Tour Guide, The Demon Seed.
  • Mulligan against Aggro (also keep if you think you are playing against an aggressive deck)Touch of the Nathrezim, Drain Soul.
  • Mulligan against Control (also keep if you think you are playing against a slow deck)Backfire.

Questline Warlock Deck Strategy

After playing The Demon Seed on Turn 1, your primary aim should be to maximise self-damage done to your Hero, while also finding opporunities to draw cards along the way, which can mostly be achieved through the use of Backfire and the Life Tap Hero Power. While drawing through your deck, you will come across a slew of discounted minions, such as Goldshire Gnoll and Flesh Giant that can freely be played when you have the Mana to do so.

As you continue through the game, you should make use of cards like Shadowblade Slinger and Touch of the Nathrezim to keep the board under control, and avoid taking damage from sources that are not your own.

As you progress through the game, you will naturally be able to close things out in one of two different ways:

  1. As you naturally play out your discounted big minions throughout the game, it is possible your opponent is unable to handle them and you can chip away at their Health. This advantage can be compounded through the use of Battleground Battlemaster to deal massive amounts of damage to unprepared opponents.
  2. Alternatively, should the game go long enough, you will eventually be able to complete your The Demon Seed Questline. Once this is done, and you are able to play Blightborn Tamsin, you can consitently chip away at your opponent's Health as you use your self-damaging effects, including fatigue damage if needed.

Against Aggro, your primary focus should be to keep the board under control. The sheer damage output of Aggro decks means that it is unlikely that you will be able to finish your Questline and should therefore play more as if you were a normal Control deck instead.

Against Control, you should expect to win with your Questline in most cases. As Control decks have an abundance of removal, it is likely they will be able to comfortably remove all of your big minions. With this in mind, when given the choice between making a board presence or progression your Questline, you should prioritise your Questline to speed up the game.
