Golgari Midrange operates on a grind-heavy plan backed by discard from Duress and recursive threats like Unholy Annex // Ritual Chamber and Tragedy Feaster, so Rest in Peace is a high-priority sideboard piece that shuts off graveyard recursion entirely. Get Lost answers problematic permanents like Ba Sing Se or Restless Cottage cleanly, giving you flexible interaction beyond sweepers. Flashfreeze hedges against their green mana acceleration and key spells like Emeritus of Abundance, leaving them tempo-negative on their development turns. Erode and Sear are trimmed as narrow removal pieces that underperform against their larger threats, and Improvisation Capstone is cut as the least impactful card in a matchup where you need consistent answers rather than combo potential. Keep your sweepers — Day of Judgment is critical for resetting their board after a resolved Llanowar Elves or Professor Dellian Fel sequence.
