Azorius Tempo leans on cheap interaction like Seam Rip, Get Lost, and countermagic (No More Lies, Three Steps Ahead) alongside sweepers like Day of Judgment, so our removal spells are often stranded with few good targets. Duress strips their countermagic or removal before we commit key threats, smoothing our path to resolving our engine pieces. Elenda, Saint of Dusk is hexproof from instants, dodging their Get Lost and other instant-speed removal while growing into a fast, resilient clock. Requiting Hex and Emptiness have few profitable targets against a deck without much of a creature base, so we trim them for proactive disruption and threats.
