Mono-Black relies heavily on graveyard value with Stitcher's Supplier, Bloodghast, Darklight Phoenix, and Agadeem's Awakening, so Soul-Guide Lantern and Ghost Vacuum proactively exile their graveyard before recursive threats come back. Scorching Shot answers their bigger bodies like a Fiend Artisan that has grown off their graveyard or the creatures Sidisi, Regent of the Mire reanimates, upgrading from Burst Lightning's more limited 2 (or kicked 4) damage. Boomerang Basics is weak here since their threats are cheap and simply get replayed, so it's not efficient tempo (a bounced Stitcher's Supplier even mills them three more cards when it re-enters). Prioritize applying early pressure since their removal suite (Annihilating Glare, Priest of Forgotten Gods) is more effective in the midgame once they have fuel.
