Nihil Spellbomb is slow and marginal here. Exiling a graveyard only touches Rancor's recursion and Sentinel's Eyes, and it does nothing to stop the auras from being cast and attached, so cut it. Duress is the single best card in this matchup, stripping Rancor, Ethereal Armor, Armadillo Cloak, or Ancestral Mask before they attach to a hexproof creature and become uninteractable. Go for the Throat stays in the sideboard: every creature Bogles plays (Slippery Bogle, Gladecover Scout, Silhana Ledgewalker) has hexproof, so it has no legal targets. Keep the full core engine, including Toxin Analysis, and race with recurring threats, since targeted removal is largely blanked by hexproof and the real answer is denying the key auras before they resolve.
