Why is Show and Tell in SB? because its totally different and unrelated to the rest of the deck except for blue mana, that's it ...
Ive tested the reanimation plan and is usually too slow or ineffective... its more tempting with the Transmute Artifact, which you cannot cast consistently, and welders will usually get killed asap anyway by these decks... zoo will sword them, sneakshow race them, with burn the turn hardcasting it you would be probably dead anyway... still it looks like a considerable SB option while playing Transmute artifact, but not to replace S&T as a whole
with grim monolith you end up with a different deck...
