Deck overview

This Golgari deck harnesses the relentless synergy of 23 copies of Slime Against Humanity led by Umori, the Collector. By naming Sorcery, Umori permanently discounts every Slime to just two mana, enabling explosive multi-spell turns. The primary win condition centers on resolving Thrumming Stone, which utilizes the Ripple 4 mechanic to chain through the library, casting dozens of Slimes in a single turn. Alternatively, Secret Salvage draws every remaining Slime directly into hand, while Surgical Extraction can target an early Slime in your own graveyard to immediately exile a dozen copies and supercharge future casts into giant 15/15+ tramplers. Supported by power-based card draw, +1/+1 counter doublers, and premier Golgari interaction, the deck rapidly establishes an overwhelming board presence that eliminates the entire table in one decisive combat swing.
