Goryo's Vengeance is a blue-heavy reanimator deck casting Goryo's Vengeance, Quantum Riddler, and multiple blue instants, so Mystical Dispute is discounted against most of their key spells and can stop the Goryo's Vengeance that reanimates Atraxa or Griselbrand. Endurance already answers their graveyard plan by shuffling it away, so we lean further into proactive interaction rather than more graveyard-dependent value creatures. Curator of Mysteries and Wistfulness are cut since they're slower and less relevant than countering the reanimation spell outright before it resolves. The core engine and Endurance stay in as our primary disruption against their graveyard-centric strategy.
