DESCRIPTION
Secrets of the Mausoleum is a deck that I built on the back of Sorin, Imperious Bloodlord and Dread Presence. Sorin makes Dread Presence have deathtouch and lifelink, and then playing a Swamp allows you to kill any creature (that isn't hexproof or indestructible), all while gaining 4 life. The Vampires all help Sorin maximize his potential, and Mausoleum Secrets allows the deck to trade early and aggressively, and then pull exactly what it needs in the late game, which is why the deck runs light on removal. It looks to tutor up exact responses to situations, rather than play a bunch of basic removal.
After Game 1, the deck sideboards into situational removal, trading out only Command the Dreadhorde, Ritual of Soot, Vraska, Golgari Queen, and Dread Presence in order to specifically shut down whatever the opponent wants to do.
