Mono-Black Creature (24) Blood Glutton x2 Demon of Loathing Fetid Imp x3 Gloom Pangolin x3 Lost Legion x3 Skeleton Archer x2 Serrated Scorpion x2 Underworld Sentinel Vito, Thorn of the Dusk Rose Walking Corpse x4 Goremand x2 Instant (8) Finishing Blow x2 Grasp of Darkness x3 Unlikely Aid x3 Sorcery (1) Enchantment (1) Land (27) Swamp x27 This mono-black deck is a good way to show off several black mechanics, but it falls short of doing any of them well

Physical cards, on the other hand, may do depending on their condition
As with most rooms, the order of play here is pretty clear
