WUR is built on the same Tablet of Discovery, Jeskai Revelation, and Great Hall of the Biblioplex shell we run, making this another grindy mirror where removal like Iroh's Demonstration has few good targets. Disdainful Stroke is well-positioned against Jeskai Revelation and Improvisation Capstone, while Spell Pierce punishes their early Firebending Lesson and Combustion Technique before they scale up with Lesson synergies. Ral, Crackling Wit adds a resilient, recurring threat that survives one-for-one removal trades. Sequence carefully around their Avengers Disassembled, which can wipe small creatures like our Monk tokens or blow up a key land.
