Omniscience Combo assembles their engine through Consult the Star Charts, Stock Up, and Kona, Rescue Beastie, then cheats Omniscience and Uthros, Titanic Godcore into play for a lethal Roiling Dragonstorm turn. Repulsive Mutation counters a key combo piece at instant speed, Oko threatens to pressure their slow setup, and Champion of the Weird provides extra disruption. Starting Town and Wistfulness are tap-lands and slow draws that waste precious tempo when you need to apply pressure and force them off their combo axis.
