4c Hollow One relies heavily on its graveyard for Vengevine returns, so Endurance's graveyard-reset trigger is disruptive to their recursive value engine while also being a flash blocker against Blazing Rootwalla and Marauding Mako. Nature's Claim directly answers Hollow One and Detective's Phoenix, as well as sideboard artifacts like Damping Sphere, keeping your interaction density up against their aggressive curve. Pact of Negation's delayed cost is dangerous against a deck this fast, and Griselbrand is too slow to matter before they close the game with hasty threats. Focus on surviving the early beats and disrupting their graveyard recursion where possible.
