This is a glass-cannon combo deck built around Neoform and Eldritch Evolution chaining into Ureni, the Song Unending or Griselbrand, so Thoughtseize on their combo setup before they can chain is our best plan. Surgical Extraction can strip every copy of a key tutor or combo piece like Summoner's Pact or Allosaurus Rider once Thoughtseize reveals their hand. Dress Down turns off Atraxa, Grand Unifier's ETB card advantage and Endurance's graveyard-hate trigger if they try to flash it in defensively. Mystical Dispute provides cheap countermagic against their blue combo spells like Neoform; cut Stubborn Denial, Street Wraith, and Drown in the Loch since we need maximum proactive disruption, not reactive value.
