Humorously, if you looked at the card for Lantern of Insight, you would think it's awful (1 mana artifact that makes both players play with the top card of their library revealed), but it's actually a namesake card of a deck (lantern control) in one of the most popular formats (Modern)!
Interesting. Yeah I just read it. I can see it being useful actually. See what's coming ahead of time and plan your counterspells and other actions around whether or not you care about the card that's coming up coming into play.
Its one of those cards that I'm not into MTG enough to be able to design a deck around, but I can see how the more hardcore players could make it work..
Is it something you played with? Seems like a good one to have purchased between the use and the cool imag.e
It actually just shuts the other player out of the game using cards that remove the top card of their (or both players) library, never giving them anything good to play. Those cards are also 1 mana artifacts, so the deck can get the lock going pretty quick. It's miserable to play against, and the control name is kind of a misnomer, it's actually a prison deck.
