Neobrand wants to chain Summoner's Pact and Eldritch Evolution/Neoform into huge creatures culminating in Atraxa, Grand Unifier or Griselbrand, so disrupting their payoffs matters. Consign to Memory counters triggered abilities from huge threats like Atraxa, Grand Unifier or Ghalta, Stampede Tyrant, while Nihil Spellbomb can strip their graveyard to deny delve costs on Hooting Mandrills. Toxic Deluge is a fine safety-valve sweeper if they overextend with creatures. Spell Snare is weak since few of their key combo pieces cost exactly 2, and Flow State is too slow against a deck that can combo off quickly.
