Jeskai Control wants to answer our threats one-for-one with Pyroclasm, Day of Judgment, Fire Magic, and Sear while refueling with Stock Up and Jeskai Revelation, so we bring in Spider-Sense to counter their key instants and sorceries (including Jeskai Revelation and their sweepers) and Voice of Victory to shut off their instant-speed interaction entirely on our turns. Lost in the Maze and North Wind Avatar are too slow or too reactive against a deck without a proactive early clock, and Prismari Charm's damage modes are weak against a control shell with few small creatures. Omni-Changeling adds a flexible late threat that dodges their narrow removal suite. Focus on resolving Omniscience or a big threat through their counterspells and use Spider-Sense to protect it from Jeskai Revelation.
