Deck overview

This deck is an Esper Sphinx tribal combo-control deck commanded by The Ur-Sphinx. It leverages passive eminence cost reduction from the command zone alongside artifact and creature cost reducers to deploy high-cost, high-impact Sphinxes far ahead of normal curve. The primary win condition is an infinite extra-turns combo between Tivit, Seller of Secrets and Time Sieve, which converts Tivit's five artifact tokens per combat/entry trigger into repeated extra turns to eliminate all opponents via flying combat damage. In backup lines, Unesh, Criosphinx Sovereign acts as a potent card-advantage engine, digging four cards deep per Sphinx cast into blink enablers like Deadeye Navigator and game-ending ETB threats like Magister Sphinx. The deck is reinforced by an elite interactive suite featuring zero-mana countermagic, asymmetric board wipes such as Raise the Palisade, and comprehensive phasing protection to ensure uninterrupted combo execution.
