Phenax, God of Deception turns every creature's toughness into a milling engine, so the deck prioritizes high-toughness defenders and large creatures to tap for massive mill each turn. The deck accelerates this plan through passive mill triggers that fire whenever you draw cards or opponents cast spells, while doubling enchantments like Fraying Sanity and Bruvac the Grandiloquent cause milled cards to cascade into exponentially larger graveyards. The primary win conditions are combo-oriented mill loops using Bruvac with either Maddening Cacophony or Terisian Mindbreaker to eliminate opponents entirely, backed by a broad suite of untap effects that let creatures tap repeatedly in a single turn. While also controlling the boardstate with kill spells, and drawing alot of cards to trigger my sphinx's tutelage, psychic corrosion, and tefer's tutelage.
