Golgari Gardens is a grindy midrange deck full of removal (Cast Down, Defile, Snuff Out) and sacrifice value engines (Fanatical Offering, Eviscerator's Insight, Ichor Wellspring), so Duress proactively strips a key removal spell or engine piece before you commit your board. This is especially valuable against Crypt Rats, whose X-damage ability can wipe your board and cannot be interacted with once activated, so removing mana or resources ahead of time helps you play around it. Cut Grim Bauble and Omen of the Dead since they are slower and less impactful against a deck this grindy compared to disrupting their hand directly. Keep your removal suite intact for their bigger threats like Troll of Khazad-dum.
