Golgari Midrange is loaded with hand disruption, removal, and sweepers like Deadly Cover-Up and Unholy Annex, so Duress lets you strip their answers or their own Duress before they can control the game. Cruelclaw's Heist proactively takes their best remaining card, denying resources in a long grindy matchup. Emptiness's -1/-1 counters are weak against their bigger bodies and Voice of Victory's tokens die easily to their removal-heavy plan, so both are cut for disruption that better matches their attrition strategy.
