Dimir Excruciator leans on Deadly Cover-Up as a sweeper that can also exile cards from a graveyard via evidence collection, so Rest in Peace shuts off that evidence collection plan and any other graveyard synergies they bring in. Jennifer Walters stops them from using removal on our turn, protecting our development plan. Michelangelo's Technique is too fragile against their discard and removal suite (Duress, Bitter Triumph), and Formidable Speaker is a reasonable cut for more disruption. Keep the full Doc Aurlock and Great Divide Guide package since grinding card advantage wins long games against control-midrange.
