Omniscience Combo relies on assembling Omniscience with Roiling Dragonstorm and Uthros, Titanic Godcore for a lethal chain. Duress strips Omniscience, Consult the Star Charts, and key tutors from their hand before they can deploy them. Annul counters their enchantment combo pieces at instant speed. Disdainful Stroke hits Omniscience and their expensive setup spells. The Unagi of Kyoshi Island provides a flash threat that applies pressure and dodges sorcery-speed interaction. Shoot the Sheriff has no relevant targets, Requiting Hex is too slow against a combo deck, and marginal flex creatures are cut to maximize your hand disruption and counter density.
