UB Reanimator wants to Dark Ritual or Lotus Petal into Reanimate/Animate Dead/Shallow Grave on Griselbrand or Archon of Cruelty, so Tormod's Crypt is a cheap way to proactively exile their graveyard before they can reanimate, though it must be timed carefully since it only hits once. Ensnaring Bridge is a weak long-term answer here since Griselbrand and Archon fly over nothing relevant to Bridge's power restriction only if their power is low, but Archon is 6 power and Griselbrand 7 power, meaning Bridge will usually stop them if our hand is empty, making it a solid backup plan. We trim Crop Rotation and Expedition Map since there's no specific land to prioritize fetching against their fast combo plan. Keep Trinisphere in, since it taxes Dark Ritual, Thoughtseize, Cabal Therapy, and Reanimate, slowing their whole sequence.
