Neobrand wants to cheat Griselbrand or Atraxa into play via Eldritch Evolution, Neoform, and Allosaurus Rider chains, so Grafdigger's Cage stops creature cards from entering the battlefield from the library entirely, shutting down their whole combo plan. Torpor Orb turns off the enters-the-battlefield triggers on Atraxa and Disciple of Freyalise, which is often how they convert the combo into a win. Cursed Totem is a lower priority but can be useful if their plan shifts toward activated abilities. Vexing Bauble stays in because Summoner's Pact and alternate-cast Allosaurus Rider are cast without spending mana and get countered by it, Sire of Seven Deaths is too slow against a combo deck that can win before we cast it, and Dismember doesn't stop the engine even though it can kill a stray creature.
