Jeskai Control aims to answer every threat with countermagic and card-advantage engines like Tablet of Discovery and Jeskai Revelation, then close with sideboard threats such as Sphinx of the Final Word. Post-board they add Flashfreeze, Disdainful Stroke, and Spell Pierce, so protecting your combo pieces is the top priority — bring in all three Spider-Sense to counter their counters and ensure Omniscience or a key threat resolves. The additional Stock Up improves your ability to find combo pieces through their disruption, and Terror of the Peaks serves as a resilient top-end threat that generates immediate value the turn it lands. Prismari Charm is too slow and mana-inefficient in a counter war, and North Wind Avatar's impact is minimal against a deck with few creatures to attack through, making them the cleanest cuts.
