Unholy Annex // Ritual Chamber

Description

Unholy Annex // Ritual Chamber (PDSK-118p) is a Room enchantment from the Duskmourn: House of Horror Promos set that offers two door halves you may cast. The front door draws a card at your end step and penalizes you unless you control a Demon, while the back door creates a 6/6 flying Demon when that door is unlocked. The card uses the Room mechanic where you cast one door and may later unlock the other by paying its unlock cost, enabling interactions with unlock‑triggered abilities.
