Omniscience Combo is a linear combo deck that wins by resolving Omniscience and chaining spells, so your priority is to apply maximum pressure as fast as possible and force them to combo off before they're ready. Mossborn Hydra comes in as a resilient, must-answer threat that grows quickly off your land-heavy strategy and demands an immediate answer. Pawpatch Formation gives you instant-speed interaction to potentially disrupt their combo turn or protect your creatures when they try to clear the board. Royal Treatment provides an additional layer of protection for key threats like Surrak, Elusive Hunter or Mightform Harmonizer. Cut the slower, incremental value pieces like Meltstrider's Resolve, Escape Tunnel, and Promising Vein, as you won't have time to leverage them — your best plan is a fast, aggressive clock.
