All players reveal the top two cards of their deck and put them back in either order.
But yeah, I unfortunately have to agree that this and the OP card are probably too situational and marginal to be worth having. I say unfortunately because it's kind of a cool idea, and potentially good flavor, to preface attacks with some information-gathering.
It strikes me as a kind of card that would become less useful the better you get at the game. Everybody has terminal collisions now and then, but as you get better at the game, you get better at minimizing that risk. When you don't have a terminal collision, do you need to gather information? Usually not. You'll play the Mountebank anyway, because, hey, +$2.
