4c HollowOne wants to discard cards via Burning Inquiry and Faithless Looting to cheat out Hollow One and recur Vengevine, so Endurance's evoke mode dumping their graveyard to the bottom of their library is devastating against Vengevine returns, though it does not affect Hollow One's cost reduction. Drannith Magistrate stops them from casting Blazing Rootwalla via madness or spells from their graveyard and generally taxes their graveyard-recursion redundancy, though note it doesn't stop Hollow One's cost reduction itself since that's a cast-from-hand discount, not an alternate cast. This matchup is a fast race, so prioritize disruption that also develops our board rather than pure answers. Trim Vizier of Remedies and Walking Ballista, our slowest pieces, for proactive graveyard disruption and a body.
