The "moldy" deck is a Historic Brawl archetype built around the commander Muldrotha, the Gravetide, utilizing a Sultai (black, green, blue) color scheme. Its primary strategy revolves around graveyard recursion, allowing the player to cast various permanent types from the graveyard each turn. This deck seeks to generate value through repeated use of powerful permanents, such as creatures with enter-the-battlefield effects and enchantments like Grave Pact to control the board. Key synergies include cards like Yarok, the Desecrated and Tatyova, Benthic Druid, which enhance the deck's ability to gain resources and board presence. Nyxbloom Ancient and The Great Henge provide mana acceleration and card draw, respectively, enabling explosive plays. Win conditions often involve overwhelming the opponent with superior board state and resource advantage facilitated by recursive threats and powerful synergies.
