Grixis Reanimator is even faster and more graveyard-dependent than Goryo's Vengeance, dumping Archon of Cruelty or Abhorrent Oculus into the yard with Faithless Looting or Thought Scour before reanimating with Unearth or Persist. Extirpate is critical, stripping their reanimation targets or Unearth itself from existence, ideally cast proactively once you see what's in their graveyard. Nihil Spellbomb offers a second, cheaper angle of graveyard hate that cantrips if drawn late. Murderous Cut is efficient removal for a resolved Archon of Cruelty once your own graveyard is stocked, while Visions of Beyond comes out since fueling both graveyards is a losing trade against a reanimator deck.
