This doesn't sound all that exciting. However, as an artifact with a similar effect has shown, knowing what the next draw would be can provide plenty of useful information. The difference between this and the Modern-playable Lantern of Insight, however, is that you can sacrifice the Lantern to shuffle a target library. Field of Dreams has no such extra ability.
Having such a similar effect though, it would seem a few players thought it may have some potential and bought copies. Suddenly having such a low supply card see sudden interest, there was a buyout. Definitely don't see this as a great investment. It's actually a great chance to sell this card if you happen to have any laying around. If you manage to find these at their old price of 5 dollars or so, then you should probably give it a shot.
The only format in which this could ever actually be good is the Old School Magic format. It's a format that only allows cards printed from Fallen Empires and before. Because of this it's often called 93/94. Could there be a sort of Lantern control deck possible in that format using Field of Dreams as an alternate version? Who knows. Someone out there must be trying it.
(Update 7/8/17: Field of Dreams' price has slowly "returned to earth" to around $30. Because it's on the reserved list, however, it's still a good card to have around.)
