Golgari Gardens leans on Ichor Wellspring and Eviscerator's Insight for repeated card draw off sacrifice; while Nihil Spellbomb and Relic of Progenitus cannot disrupt the Ichor Wellspring graveyard trigger, they disrupt Eviscerator's Insight's flashback, though Fanatical Offering and Eviscerator's Insight draw cards independent of the graveyard so they aren't fully stopped. Suffocating Fumes' -1/-1 is underwhelming against their higher-toughness threats like Troll of Khazad-dum, so trim it. Keep Cast Down at full strength since it's an efficient answer to Crypt Rats and Troll of Khazad-dum, though Snuff Out cannot target either since they are black creatures. This is a grindy black mirror-adjacent matchup where card advantage from Lorien Revealed and Brainstorm should carry you.
