Claim the Firstborn and Bloodtithe Harvester's removal mode are weak against Golgari's high-toughness threats like Sheoldred, the Apocalypse and Sentinel of the Nameless City, so trim them for proactive disruption. Thoughtseize strips their removal or Sheoldred before it lands, which is crucial since our deck folds to unanswered Sheoldred. Ghost Vacuum and Go Blank fight their graveyard synergies (Graveyard Trespasser, Unholy Annex) and can exile recursive threats before they matter. Keep the full Fatal Push and Mayhem Devil package since their board is full of cheap creatures and planeswalkers our sacrifice engine punishes well.
