Hogaak, Arisen Necropolis can be cast from the graveyard via delve/convoke and relies on Stitcher's Supplier self-mill, so Rest in Peace is the key hate card here. It exiles all graveyards on entry and exiles every card that would hit a graveyard afterward. That removes the cards Hogaak delves away, stops it from sitting in the graveyard to be recast, and keeps Dark Matter Manipulator from growing. Hogaak can still be cast from hand with convoke, but without delve it is far harder to deploy. I'm not bringing in Containment Priest. It only exiles nontoken creatures that enter without being cast, and Hogaak cast from the graveyard is still cast, so Priest does not stop it. Solitude is weaker here because Daze and Force of Will punish evoking it for tempo, so one copy comes out. Sheltered by Ghosts is also a lower priority since they have few key noncreature permanents to lock down. Keep Chalice of the Void in. At X=1 it counters Ponder, Brainstorm, Fatal Push, Stitcher's Supplier, Dark Matter Manipulator and Moonshadow. At X=2 it counters Daze, Orcish Bowmasters and Wail of the Forgotten. It does not hit Daze (mana value 2) or Force of Will (mana value 5) at X=1.
