Dimir Excruciator relies on huge graveyard-fueled reanimator plays like Bringer of the Last Gift and big creatures such as Superior Spider-Man and Terror of the Peaks. Duress can strip removal like Bitter Triumph or a key enabler before they set up their engine. Professor Dellian Fel's -3 provides repeatable, efficient removal for their large threats without needing the extra cost that Deadly Precision requires, and its lifegain mode helps race Bringer of the Last Gift's board wipe. We cut Fanatical Offering, which is risky when Bringer of the Last Gift can reset the board anyway, along with Deadly Precision for the more mana-efficient planeswalker.
