Deck overview

This deck is an Esper kindred-combo hybrid centered on The Ur-Sphinx, leveraging eminence cost reduction, high-velocity fast mana, and efficient tutors to deploy oppressive Sphinx engines or execute compact game-ending combos. The primary win line utilizes Thassa's Oracle paired with Demonic Consultation or Tainted Pact, reliably assembling on Turn 3 for an immediate same-turn win. Alternatively, the deck can establish an infinite extra-turn engine through Tivit, Seller of Secrets and Time Sieve, generating five artifact tokens per trigger to fuel uninterrupted turns and lethal evasive damage. A dense package of high-impact Sphinxes—including Consecrated Sphinx, Unesh, Criosphinx Sovereign, and Magister Sphinx—provides immense card advantage and combat pressure as a resilient tertiary route. Supported by premium Esper interaction, free counterspells, and reanimation redundancy, the deck maintains high operational velocity and seamless transitions between explosive combo finishes and compounding midgame value.
