Sneak and Show wants to cheat in Atraxa, Grand Unifier or Emrakul, the Aeons Torn via Show and Tell or Sneak Attack, so Spell Pierce is excellent against their noncreature enablers while Consign to Memory stops Sneak Attack's activated ability-adjacent plan is actually not countered by it since that's an enchantment's activated ability triggered later, so Consign to Memory mainly protects us from a triggered ability or colorless spell instead; keep it in for flexibility against Lotus Petal-fueled starts and any colorless threats. Echoing Truth can bounce a resolved Show and Tell target like Atraxa before it does lasting damage. We trim slow cantrips and the fragile Pinnacle Emissary for proactive disruption since this matchup is a race to disrupt their combo before turn three or four.
