Neobrand is a fast combo deck that chains Summoner's Pact, Neoform, and Eldritch Evolution into a game-ending Griselbrand or Atraxa, so Thoughtseize is essential to strip their combo piece or a key enabler before they can assemble it. Vexing Bauble counters free spells like Summoner's Pact and Allosaurus Rider when cast for its alternative cost, buying time to race. Lightning Bolt and Violent Urge are weak since removal doesn't meaningfully slow down a deck that wins through a single big creature attack or value engine rather than combat damage from small creatures. Race aggressively while stripping their hand, since letting them untap with a full combo turn is usually fatal.
