Deck overview

This deck is a Grixis combo-control list helmed by Mairsil, the Pretender, designed to assemble game-winning combinations of activated abilities in exile. The early game focuses on stocking the graveyard with specialized creature and artifact payoffs using Buried Alive, Entomb, and efficient looting spells. On Turn 4, Mairsil enters the battlefield and cages a key piece, often prioritizing Aetherling for self-protection or Asmodeus the Archfiend for massive card draw without its drawback. Over subsequent turns, blink spells and flicker abilities allow Mairsil to cage additional pieces, including Quicksilver Elemental, an untapper, and a mana source or direct damage dealer. Once assembled, Mairsil bypasses his once-per-turn activation limit through Quicksilver Elemental to generate infinite mana and burn the entire table on Turn 6. The deck supports this game plan with free interaction, boots for haste and protection, and board-wiping utility engines.
