Azorius Tempo leans on enter-the-battlefield value from Nurturing Pixie, Haliya, Guided by Light, and Starfield Shepherd, so Torpor Orb is a strong answer that shuts off all of these enters-the-battlefield triggers. This slows their life-gain-into-card-draw engine and their curve significantly. Ghost Vacuum is a minor inclusion against incidental graveyard value. Cut Lodestone Needle and Spring-Loaded Sawblades since Azorius Tempo doesn't overload the board with cheap artifacts or creatures that these answer best, keeping the plan focused on disrupting their triggered abilities.
