This is the exact mirror image sacrifice matchup, so it comes down to grinding value and removing key threats. Professor Dellian Fel's -3 kills their best creatures (Umbral Collar Zealot, Magda) and the +2/0 modes help you stabilize and out-value their card draw engines. Duress preemptively strips their own Strategic Betrayal or Professor Dellian Fel before they can deploy it. Requiting Hex only hits creatures with mana value 2 or less, and Deadly Precision's extra cost is often too slow against another aggressive sac deck, so we trim the more conditional removal for higher-impact planeswalker value and disruption.
