Kraum, Ludevic's Opus / Tymna the Weaver

How it plays & wins

This is a blue-black-red cEDH list that runs a huge amount of fast mana, including Mana Vault, Grim Monolith, Chrome Mox, Mox Amber, Lotus Petal, and Dark Ritual. It uses that mana to power tutors like Demonic Tutor, Vampiric Tutor, Mystical Tutor, and Enlightened Tutor, plus card advantage from Necropotence, Ad Nauseam, Rhystic Study, and Mystic Remora. Kraum and Tymna add a steady stream of cards while the deck keeps its hand full of cheap interaction like Force of Will, Fierce Guardianship, Pact of Negation, and Misdirection.

The most direct win is an empty-library finish: Demonic Consultation or Tainted Pact into Thassa's Oracle. Its backup plan is Underworld Breach with Lion's Eye Diamond and Brain Freeze, where you cast spells from the graveyard to build storm. You protect either line with free counters, so the game usually ends in a single turn.
