Step into the Unholy Annex

Unholy Annex / Ritual Chamber matches the Duskmourn tone by offering a practical room effect that rewards timing and commitment. Unholy Annex is a compact enchantment that pressures your upkeep and asks you to plan your hand and mana ahead. Play it when you need a steady engine that either fuels a sacrifice plan or unlocks for a decisive board swing. Experienced players will appreciate how the card pushes resource sequencing and creates tight, repeatable value across turns.

Flip the door to Ritual Chamber when the moment is right and you get a clean payoff. Ritual Chamber produces a sizable flying Demon token on unlock which finishes stalled races and closes out aggressive decks. The two faces read together like a short chain of actions: lock the room, leverage incremental advantages, then unlock for a big threat. Add this Light Play Foil borderless print to any Duskmourn collection for both play and display; it reads clearly in hand, plays well in midrange and sacrifice shells, and fits thematically into any black heavy build. Grab one now to tune your deck for late game finishes.
