Force of Will: Nothing to argue about here; we play a blue deck that needs protection so we play a playset of Forces.
0-3
Misdirection: It makes our bad matchups better, while being dead against things like Maverick (where it can only be a Force pitch or change the target of a swords if you’re running creatures other than Emmy or Proggy). But the fact that it is so strong against discard, which hurts us a lot, and that it acts as a Force of Will against a counterspell makes it necessary to test in your environment.
0-4
Daze: Seen by some as controversial in Sneak Show. While it is nice for countering a turn 2 Knight of the Reliquary, it does set us one turn back if it’s not used while going off. Especially when it has to counter an opposing Careful Study or an Aether Vial,
Spell Pierce is often more effective (that is, if you didn't ponder turn 1). Daze can be very strong in game 1 and many lists play 3 Daze main and 3 Spell pierce to replace them post-board if needed.
0-3
Spell Pierce: Many players opt for Spell Pierce over Daze in the maindeck. Most that don't run them main include some number in the board. (See sideboard section.)
0-3
Flusterstorm: Some prefer Flusterstorm over Spell Pierce because it's more effective against counters/discard/storm strategies/everything that matters against us in the current meta outside of
Liliana of the Veil and Jace, the Mind Sculptor.

Jace, the Mind Sculptor: Serves a variety of functions, including protection, and is popular with some players. Proponents argue that he a) draws out counters, further ensuring successful resolution of the combo; b) buys time by digging or bouncing while preparing to go off, in effect gaining life while solidifying the combo; c) opens up the option of bouncing Emrakul after a Sneak Attack assault; d) provides protection when putting creatures in off of Show and Tell, marginalizing any creature that they choose; e) and is an out to opposing Jaces. Opponents argue that he is too often a 4 mana sorcery speed brainstorm or
echoing truth that gains 3-4 life, and that his slots are better filled by more counters or acceleration. Uniquely, Sneak Show offers a consistent turn 3 Jace. Ultimately, it comes down to play-style preference. Lists running Jace tend to combo out (slightly) more slowly, but gain some versatility and interactivity that the strategy otherwise lacks.
