Grixis Reanimator wants to discard Archon of Cruelty or Abhorrent Oculus via Faithless Looting or Psychic Frog and bring it back with Unearth or Persist, so Surgical Extraction and Tormod's Crypt are essential to strip their graveyard before or after they discard the threat. Consign to Memory protects your tempo plan and can counter their Unearth or a key enabler at instant speed. Cut Mishra's Bauble since it feeds their own graveyard-adjacent plan for free, and Boomerang Basics since they have few standalone permanents worth bouncing while you need every slot for graveyard disruption.
