Saga Storm vs Sneak and Show

Sneak and Show is a glass-cannon combo deck racing to resolve Sneak Attack or Show and Tell into Emrakul, the Aeons Torn or Atraxa, Grand Unifier, so our Thoughtseize and Cabal Therapy are already well-positioned to strip their payoff pieces. Surgical Extraction is a low-cost swap that can exile a copy of Sneak Attack or Show and Tell from hand/graveyard/library after we see one, functionally acting as a one-sided answer to their redundancy. We cut Duress rather than Thoughtseize since Thoughtseize is unconditional and hits their whole hand, while Duress misses creatures like Emrakul, the Aeons Torn if it's ever drawn naturally.
