Mono-Black Reanimator-aggro runs a lot of cheap mana value 1-2 creatures (Eyetwitch, Stitcher's Supplier, Dark Matter Manipulator, Bloodghast) that Fatal Push answers for a single mana, which is far more efficient than relying on Torch the Tower's conditional 2-3 damage. Duress strips their own Thoughtseize or a key piece like Agatha's Soul Cauldron before you tap out into artifacts. Voldaren Epicure's 1/1 body trades poorly into their removal-dense, grindy black deck with Annihilating Glare and Fatal Push of their own, so trimming for better interaction is correct. Watch for Darklight Phoenix recursion and prioritize answering their sacrifice engine (Priest of Forgotten Gods, Fiend Artisan) before it snowballs.
