Goryo's Vengeance wants to discard and reanimate Griselbrand or Atraxa, Grand Unifier, so hitting the graveyard plan directly is your best angle. Grafdigger's Cage completely shuts off Goryo's Vengeance from returning anything to the battlefield and also stops Emperor of Bones-style tricks, making it one of the best cards you can bring in. The second Vexing Bauble helps disrupt their free-cast Force of Negation and Solitude, since Force of Negation is often cast for free and Solitude can be evoked for free by exiling a white card. Warping Wail gives you cheap interaction against their Psychic Frog or a way to counter a key sorcery like Living End-style Goryo's Vengeance is an instant so Wail's counter mode won't hit it, but it still answers small creatures. Unholy Heat loses value since their real threats (Atraxa 7/7, Griselbrand 7/7) are far outside its reach even with delirium, so it's cut for more targeted graveyard disruption.
