The "mill3" deck is a Sultai (blue, black, green) Commander deck with a primary strategy focused on self-mill and graveyard recursion. The deck aims to fill its own graveyard with powerful creatures and spells, then leverage this resource for value and victory. Key cards like Muldrotha, the Gravetide and The Gitrog Monster allow for recurring plays from the graveyard, while Laboratory Maniac offers an alternate win condition if the library runs out. Glimpse the Unthinkable, Mesmeric Orb, and Hermit Druid facilitate the mill strategy. The deck utilizes creatures like Sidisi, Brood Tyrant and Lord of Extinction to capitalize on the graveyard's size, potentially overwhelming opponents. Defensive tools like Heroic Intervention and Pernicious Deed protect and control the board as the deck builds towards its endgame. Overall, this deck is a graveyard-centric, recursion-based strategy that aims to win through resource advantage and potent, graveyard-fueled threats.
