UBG Reanimator wants to Dark Ritual or Lotus Petal into Animate Dead, Reanimate, or Shallow Grave to cheat Griselbrand, Atraxa, Grand Unifier, or Archon of Cruelty into play early. Tormod's Crypt exiles their graveyard before they can reanimate a discarded fatty, which is often the single best answer to their plan. Haywire Mite can exile a resolved Animate Dead, which forces them to sacrifice the reanimated creature because the Aura left the battlefield. It can't answer Reanimate or Shallow Grave, since those spells go to the graveyard on resolution, and it needs {G} to activate. Lightning Bolt helps us close games quickly since this matchup can become a race if their graveyard plan is disrupted.
