4c Artifacts wants to assemble artifact synergies like Simulacrum Synthesizer triggering Construct tokens and set up Pinnacle Starcage to exile our low-cost permanents, so Duress strips a key artifact enabler or answer before it locks in. Requiting Hex whiffs on most of their bigger threats and card advantage artifacts, so it steps out in favor of proactive hand disruption that slows their engine before it compounds.
