Azorius Tempo's game plan revolves around flyers like Momo, Sage of the Skies, and Starfield Shepherd backed by card selection from Steamcore Scholar and Quantum Riddler, so Torpor Orb turns off Steamcore Scholar's draw-two, Quantum Riddler's draw, and Starfield Shepherd's tutor, along with any other enters-the-battlefield triggers on the creatures they bring in. Disdainful Stroke gives you a clean answer to their five-mana threats like Quantum Riddler and Starfield Shepherd, and Negate handles their noncreature spells like Daydream, Practiced Offense, Erode, and Get Lost. Both are more valuable here than Duress, since they run almost no removal to strip from their hand and a mostly low-curve creature plan. Firebending Lesson comes out because 2 damage rarely kills their bigger bodies like Quantum Riddler or Guiding Hydra, while Fire Magic and Sear remain in the maindeck as better answers to their small flyers. Keep Jeskai Revelation and the Verge lands as the backbone, since the card advantage and 4 damage line up well against their token and flyer-based aggression.
