4c HollowOne wants to dump its hand via Burning Inquiry and Faithless Looting to cheat out Hollow One and bring back Vengevine, so Dismember gives us cheap removal for their aggressive threats like Blazing Rootwalla or Marauding Mako before they get out of hand. Grafdigger's Cage is much more impactful here than our maindeck Soul-Guide Lantern since it stops Vengevine from returning from the graveyard and prevents Detective's Phoenix from being cast from the graveyard, directly attacking their core recursive gameplan. Soul-Guide Lantern and Haywire Mite are cut since Grafdigger's Cage is a strictly more comprehensive graveyard answer against their recursive creatures, and Springleaf Drum is low-impact against a fast aggressive deck. Racing is close, so prioritize removal and graveyard hate over incremental mana development.
