The Epic Storm relies on a mountain of zero and one-mana artifacts like Lotus Petal, Chrome Mox, and Mox Opal plus Lion's Eye Diamond to chain into Tendrils of Agony, and Consign to Memory with replicate can counter multiple of these colorless spells in a single storm turn. Surgical Extraction can proactively remove their copy of Tendrils of Agony or a key piece like Lion's Eye Diamond from hand, graveyard, and library before they combo off. Forth Eorlingas!, Wrath of the Skies, and Dress Down do nothing relevant against a deck with almost no creatures to interact with. Keep Force of Will, Force of Negation, and Spell Pierce as your primary ways to disrupt their combo turn.
