Chancellor of the Annex is a weak soft-counter here since it only stops one unpaid spell and the opponent generates mana surplus easily via Lotus Petal, City of Traitors, and Ancient Tomb to pay the tax. Disruptor Flute naming Aluren, Show and Tell, or Omniscience taxes their key payoff spells by {3}, which is far more impactful against a deck trying to assemble a specific combo piece. Trinisphere and Chalice of the Void remain excellent, disrupting their Lotus Petal, Brainstorm, and Ponder mana base. Keep the full proactive creature suite since this matchup is a race to close the game before they resolve Show and Tell or Aluren.
