Doomsday is a pure combo deck assembling a five-card stack to win with Thassa's Oracle, so our best plan is maximizing disruption on their combo turn rather than boarding for creatures. Surgical Extraction can target a key piece like Lion's Eye Diamond or Thassa's Oracle in their graveyard to strip copies from their hand and library, denying them the ability to find or execute their kill even after a Doomsday resolves. Wrath of the Skies and Solitude are both dead or near-dead since they run almost no creatures worth killing, so those come out in favor of graveyard disruption; our free counters Force of Will and Force of Negation remain the core of this plan.
