Sneak and Show wants to resolve Show and Tell or Sneak Attack and immediately put Griselbrand, Emrakul, or Atraxa into play, so disruption and interaction matter more than our normal creature synergies. Gaddock Teeg shuts off Sneak Attack and Omniscience, since both are noncreature spells with mana value 4 or greater. It does not stop Show and Tell, which costs three mana, so we still need to pressure them or disrupt them before they cast it. Teeg also stops our own Natural Order and Green Sun's Zenith, so deploy it with that in mind. Endurance gives us a flash 3/4 reach blocker, and its enters ability can put a creature like Griselbrand or Atraxa that was sacrificed to Sneak Attack from their graveyard onto the bottom of their library. Sylvan Safekeeper, Collector Ouphe, and a Badgermole Cub are less relevant here since the opponent has little targeted removal and Lotus Petal is their only real artifact to interact with.
