Unlock the Annex, Summon the Chamber
Unholy Annex / Ritual Chamber is a split Enchantment Room from Duskmourn House of Horror that rewards board development and timing. Unholy Annex sits quiet until your end step when it pressures card advantage and life totals. At the beginning of your end step draw a card and if you control a Demon each opponent loses two life and you gain two life otherwise you lose two life. That decision point makes the Annex a reliable engine in creature heavy black decks and a tempo liability in lean lists.
Ritual Chamber reads as a payoff for unlocking the door. As a sorcery you may unlock the Chamber to create a six six black Demon creature token with flying. The modal cast lets you choose the route that fits the game state. Use the Annex to convert a recurring Demon presence into steady advantage or unlock the Chamber when a big flier will close the game. Add this Medium Play foil to your collection to round out a Duskmourn themed build or to slot into sacrifice, Aristocrat, or tribal Demon shells. Pick the tactic that matches your curve and unlock consistent value.
