Sneak and Show wants to resolve Show and Tell or Sneak Attack into Emrakul, the Aeons Torn or Atraxa, Grand Unifier, and Force of Negation lets us answer that enchantment for free even on their turn. Consign to Memory is colorless-spell-and-trigger hate that covers their Lotus Petal-fueled starts and any Clue-style triggers along the way. We trim the low-impact cantrip artifacts and the taxed Metallic Rebuke, since we need maximum free, proactive disruption rather than mana-intensive answers in a matchup decided by a single turn. Hold up mana for Force of Will and these new counters on their turn whenever possible.
