Deck overview

This Esper deck blends Sphinx tribal synergies with an artifact-based Powerstone ramp engine, led by The Ur-Sphinx. The commander's eminence ability reduces the cost of Sphinx spells throughout the game, allowing the deck to deploy large flying threats ahead of curve. The early game focuses on setting up mana rocks, Powerstone generators like Urza, Powerstone Prodigy, and defensive enchantments like Ghostly Prison and Propaganda to deter aggression. By turn 5, the deck transitions into its midgame engine, utilizing Urza, Lord High Artificer, Elenda and Azor, or Urza's Incubator to maximize mana efficiency and card flow. The endgame lands devastating high-cost permanents on turn 6, such as Magister Sphinx or Portal to Phyrexia, followed by casting The Ur-Sphinx to mill opponents and cast free spells on attacks. The deck secures victory through overwhelming flying combat damage across turns 7 to 9.
