Leyline of the Void can be put onto the battlefield for free from our opening hand, exiling the creature cards they try to reanimate via Reanimate, Animate Dead, or Shallow Grave, which is a total answer to their entire plan of cheating Griselbrand or Atraxa, Grand Unifier into play. The extra Thoughtseize adds to our 3 mainboard copies to proactively strip their Dark Ritual, Reanimate, or Animate Dead before they can combo off. We cut Crop Rotation, Sylvan Safekeeper, and Elvish Reclaimer since grindy land-value plans don't matter if they reanimate a 7/7 flyer on turn two; disruption and graveyard hate are what win this matchup.
