A Grixis mill deck that grinds opponents' libraries away and then turns their graveyards into a resource. Lord Xander, the Collector is the centrepiece: his entry strips half a hand, each attack mills half a library, and his death forces half of a board to be sacrificed. Mill amplifiers, draw-triggered mill enchantments and a reanimation package that steals creatures out of the stuffed graveyards push the plan forward. How it wins: It empties opponents' libraries with Xander attacks, half-library mill spells and amplifiers like The Water Crystal and Fraying Sanity, or loops The Mindskinner with Syr Konrad, the Grim, or turns mass mill into life loss with Duskmantle Guildmage. Key roles: - Half-library attackers: Lord Xander, the Collector and other attackers carve away half a library per swing, and copy and recast effects get extra value out of the commander's enter, attack and death triggers. (Fleet Swallower, Terisian Mindbreaker, Geode Golem) - Mill bursts and amplifiers: Big one-shot mill spells empty libraries quickly, while amplifiers add extra cards to every mill event or repeat a turn's mill at end step. (The Water Crystal, Fraying Sanity, Maddening Cacophony) - Draw-triggered and passive mill: Enchantments and small creatures turn ordinary card draw, spell casting and land drops into steady mill every turn. (Psychic Corrosion, Teferi's Tutelage, Ruin Crab) - Graveyard reanimation and theft: Once opponents' graveyards are full, it puts their best creatures onto its own battlefield or casts their milled cards, fitting the reanimator intent. (Breach the Multiverse, Extract from Darkness, Thief of Sanity) - Graveyard-scaling threats: Creatures that grow with the number of cards in opponents' graveyards become huge as the mill plan progresses. (Consuming Aberration, Cruel Somnophage, Wight of Precinct Six) - Damage-to-mill combo engines: Combat damage and pings are converted into mill, and milled cards are converted into life loss, creating self-feeding loops. (The Mindskinner, Syr Konrad, the Grim, Duskmantle Guildmage)
