mtg house of horror card list Unholy Annex // Ritual Chamber (DSK-118) draw a card Duskmourn: House of Horror Commander

Illustrated by Jesper Ejsing Unreleased This card will be released on 2026-10-02, it is not legal in any format until its release date approaches

If you want to activate a library ninjutsu ability while searching your library, you must do so before you find any cards with the search effect

Defensive effects are a must in the game, but an incredibly pushed card like Mithril Coat might actually cause problems, and its downsides are negated in the Commander format

There are also commanders that exploit life loss, with Ob Nixilis, Captive Kingpin, Valgavoth, Harrower of Souls, and Rakdos, Lord of Riots (its a very Rakdos-coded mechanic)

So, if your opponent has both poison and energy counters, you can give them one more of each or none

At large events like PAX, you can find deals on boxes that vendors cant move locally
