Rograkh, Son of Rohgahh / Silas Renn, Seeker Adept

How it plays & wins

This is a turbo-style blue-black-red deck built on a huge pile of fast mana: Moxen, Sol Ring, Mana Vault, Lotus Petal, rituals and Simian Spirit Guide. It uses that mana to power out cheap tutors like Vampiric Tutor, Mystical Tutor and Demonic Tutor, and to dig with Necropotence and Ad Nauseam. A suite of free interaction, including Force of Will, Fierce Guardianship, Force of Negation, Pact of Negation, Misdirection and Flusterstorm, protects the final turn. The commanders are a cheap partner pair that give access to all three colors and serve as backup plays.

The most direct wins are Thassa's Oracle paired with either Demonic Consultation or Tainted Pact, which empties the library and wins on the spot. The backup plan is Underworld Breach with Lion's Eye Diamond, finishing with Brain Freeze. The list has other powerful engines, but those two lines are the clear ones.
