This is a fun to play Monk deck that uses Altar of Despair and Journey to Sovngarde.

Of any archetype you can pick to make a Journey to Sovngarde deck work, Monk has the easiest time with drawing cards, gaining health, and using creatures to keep the board clear, while also having access to an alternate win condition using Bruma Profiteer, Altar of Despair and Protector of the Mane.

One thing you’ll notice is this is a creature deck with only three supports and four actions. All the removal, card draw and health gain in the deck is going to be through creatures. This is a decision to fill the discard pile with creatures quickly. Also, the flow of creatures stops at six magicka. This is an early cliff for an Altar deck, which usually wants to summon big monsters eventually, but that’s not how the Altar works here. The goal is to send creatures to the grave with it. The win condition is through cycling them back into the deck and playing them a second time, heavily buffed. The only card Thieves Guild Recruit can retrieve that will have its cost reduced is Journey to Sovngarde. Every creature in your discard pile will cost 0 when they’re shuffled back into your deck. That event makes Goblin Skulk important.

This is a fairly budget conscious deck. If you’ve picked up the Madhouse Collection, Fall of the Dark Brotherhood and have the Monthly Reward card for Monk, there isn’t much else you really need to craft.
Journey to Sovngarde… Because the deck digs for it, it sees play in most matches, so crafting it won't feel too bad.
