Amulet Titan wants to chain bounce-lands and cast Primeval Titan or use Scapeshift to assemble a fast mana base, and Grafdigger's Cage shuts down any creature recursion while also hitting Green Sun's Zenith's search by preventing the found creature from entering the battlefield since it wasn't cast. Nihil Spellbomb is a cheap way to interact with Shifting Woodland's graveyard copy ability and denies general graveyard value. Street Wraith's swampwalk is dead against a deck with no Swamps, making it the natural cut. Keep Thoughtseize maximally active to strip their Scapeshift or Primeval Titan before they can go off, since this deck is explosive once it resolves a big land-fetching spell.
