Deck overview

This deck is a high-velocity Esper Sphinx tribal build commanded by The Ur-Sphinx. The list breaks singleton variance by running 25 copies of Sphinx's Approach, which act both as repeatable cantrips and an engine that tutors giant Sphinxes directly onto the battlefield once five copies enter the graveyard. With The Ur-Sphinx providing eminence cost reduction, the deck smoothly deploys engine pieces like Sphinx of the Chimes and Unesh, Criosphinx Sovereign on turn 4. Drawing deeply through duplicate Approaches fuels explosive turn 5 turns that cheat into play game-ending threats such as Magister Sphinx and Medomai the Ageless. Combat damage from Medomai secures an extra turn, enabling the massive airborne armada to defeat all three opponents by turn 6. The deck trades broad reactive interaction for hyper-consistent execution, rapid engine recovery, and overwhelming aerial combat power.
