“Fill your deck with Souls, cycle fast and whittle down foes”
Core idea
Dirge is a fantastic source of Souls, especially when upgraded, granting defence, utility and scaling. Souls have many damage activators it can pair with: Death March pairs excellently with Souls build and can often unleash huge damage after your first deck cycle, though can be inconsistent with poor draws; Haunt is a safer more consistent damage source, though less powerful in multi enemy encounters due to its inability to target one foe down quickly; Soul Storm scales consistently for big targeted swings, but can take longer to get set up. An alternative win condition is Gold Axe, scaling quickly from the sheer amount of Souls played.

Support plan
Necrobinder has a bunch of Soul generation cards. Automation is a great addition for regular energy generation, but very little beats Borrowed Time. Cards that can be played freely can help keep your deck flowing, otherwise your hand may become too full to be able to get maximum efficiency from your draws. Deathbringer can help solve some area damage and Weakness that the deck lacks. Devour Life and Dirge pair well with Unleash as an alternative damage source, outshining Death March with enough support.

Weaknesses
This deck has no synergistic ways to deal with multi enemy encounters, so be sure to pick up a couple of simple sources. Curses like Regret can heavily punish big draws, and some Status heavy enemies like the Soul Fysh can prove challenging. The Knights act 3 elite fight can punish you for overdrawing, potentially burning key cards. In theory Eidolon is a strong source of defense, but I don't find the card powerful enough at present to be worth the pick.
