Golgari Gardens wins through artifact-fueled card advantage — Ichor Wellspring, Nihil Spellbomb, Lembas, Tithing Blade, and Campfire all generate value — so Deglamer and Dust to Dust come in to dismantle that engine efficiently, with Dust to Dust hitting two artifacts at once for just three mana. Guardian of the Guildpact is your premier threat in this matchup since protection from monocolored makes it completely immune to their entire removal suite (Cast Down, Defile, Snuff Out) and even Crypt Rats pings, so protect and grow it with Armadillo Cloak whenever possible. Prismatic Strands is critical to keep: if you have a white creature in play when Crypt Rats activates, you can prevent all the damage to your whole board, potentially blowing out their sweeper. Malevolent Rumble and Midnight Tilling are cut as the slowest cards in the deck — you need to be answering their artifacts and threatening them with protected beaters rather than building incremental card selection. Their sideboard Faerie Macabres trade with yours if you're using the hand-exile ability, but Bojuka Bog and Witch's Cottage recursion are minor concerns here compared to the artifact value engine.
