Azorius Tempo relies on cheap flying threats like Momo and Sage of the Skies plus removal in Seam Rip and Get Lost, so Duress can strip a removal spell or disruption piece before it matters. Bloodthirsty Conqueror's flying and deathtouch let it trade profitably with their evasive fliers, and whenever an opponent loses life (for example from the drain on Lunar Convocation or Starscape Cleric) you gain that much life. Enlightened Confidant is a fragile 2/1 that dies easily to their efficient removal and doesn't block fliers, and Essence Channeler is another small 2/1 that their cheap removal answers just as easily. Prioritize surviving the early air assault and stabilizing with lifegain triggers into the long game.
