Sorcerous Spyglass - 2
Artifact - R
As Sorcerous Spyglass enters the battlefield, look at any opponent's hand, then choose any card name.
Activated abilities of sources with the chosen name can't be activated unless they're mana abilities.
A leak of a foil rare sheet just hit Reddit, and this card seems tailored perfectly for use in Vintage. Workshops can make some very real sideboard use out of a Pithing Needle that dodges Mental Misstep and creature removal, but does the inclusion of free information make it maindeck worthy? After all, leading on this against a deck running fetchlands could put your opponent out of the game nearly immediately.
