Goryo's Vengeance is a heavily blue deck (Quantum Riddler, Psychic Frog, Faithful Mending, Force of Negation) so Mystical Dispute is live constantly and cheap; it can stop their Goryo's Vengeance reanimation plan or a key Ephemerate/Solitude. The extra Veil of Summer protects your combo pieces from their Thoughtseize and Fatal Push while also blanking their countermagic like Spell Pierce and Force of Negation. Disciple of Freyalise and Nourishing Shoal are clunky since this matchup is about disrupting their graveyard plan and not about racing life totals, and Generous Ent is too slow. Endurance remains excellent maindeck since it can put all cards from their graveyard on the bottom of their library to stop Goryo's Vengeance from reanimating Atraxa, Grand Unifier or Griselbrand.
