This is a mirror-adjacent matchup where the opponent's plan hinges on resolving Goryo's Vengeance to reanimate Griselbrand or Atraxa; Force of Negation is a free counter on their turn that stops the Goryo's Vengeance itself or any other noncreature spell like Prismatic Ending. Consign to Memory counters triggered abilities, so it can strip the value off an Atraxa enters trigger or similarly relevant triggers, and it can also stop colorless spells. Since games go long and both sides grind card advantage, trim Faithful Mending and Persist slightly for more interaction, keeping your core Thoughtseize/Solitude disruption suite intact to fight over their key reanimation spell.
