Force of Negation is a premium free counterspell against their Goryo's Vengeance itself or a follow-up Ephemerate/Faithful Mending, disrupting their reanimation plan before Atraxa or Griselbrand ever hits the battlefield. Thoughtseize proactively takes their Goryo's Vengeance, Atraxa, or a piece of interaction like Solitude before it matters. Consign to Memory answers Orcish Bowmasters-style pings are not applicable here, but it does stop colorless spells and triggered abilities like a Quantum Riddler warp trigger or graveyard recursion triggers. Erayo and Basim die easily to their removal suite (Fatal Push, Solitude) and don't interact with their combo plan, so they're cut for interaction that can stop their reanimation plan before it swings the game.
