Leyline of the Void shuts off Murktide Regent's delve and cripples the Nethergoyf/Moonshadow graveyard synergies while denying Bilbo, Thief in the Night's graveyard casting engine. Disruptor Flute is excellent naming Force of Will or Daze to blunt their free countermagic, or naming Wasteland to protect our Urza lands. We trim Mox Opal since it dies easily to Wasteland pressure and doesn't do much when they're taxing our mana, and cut the marginal one-ofs. Keep the core combo pieces intact since we still need to assemble Karn/Trinisphere/The One Ring through their disruption.

Ensnaring Bridge is very strong here since our hand is often near-empty from casting spells, and their aggressive board of Cat tokens and other creatures generally have power greater than our card count, shutting down their attacks. Engineered Explosives can sweep their cheap X=1 threats like Guide of Souls or Ocelot Pride when we spend just one color of mana casting it. We keep Trinisphere in since it severely punishes their one-mana disruption suite (Static Prison, Swords to Plowshares) and cheap threats, forcing them to pay three mana for everything.

Faerie Macabre can exile up to two targeted cards from a graveyard when discarded, and Silent Gravestone can lock down graveyards, but our own Tormod's Crypt is already in the sideboard and doesn't need duplicating here since Acererak the Archlich returns to hand rather than dying, so graveyard hate doesn't disrupt its rebuys. Soul-Guide Lantern already does graveyard work mainboard if needed against other matchups, so no extra graveyard hate is worth bringing in against this deck. Keep the artifact mana base and Trinisphere plan intact since Trinisphere is excellent at taxing their cheap enablers like Lotus Petal.
