Yup. One of the most interesting things Vintage does for me is seeing cards that were originally rarely played when released becoming bombs now that they interact with a card considered unplayable in a new set. A perfect example for me was what happened to flash when newer creatures came out. I've had a playset of them since Mirage as I bought a bunch of it when it came out. They just sat in my binder.
Good sentiment, bad example. Flash was reworded in May 2007 to break it just in time for a Legacy Grand Prix in Columbus. The two main creatures that helped to break it, Academy Rector and Protean Hulk, were printed in February 1999 and May 2006 respectively.
The only cards that seem to have any real potential are Underworld Breach and Soul-Guide Lantern.
Breach is very exciting, although we'll have to see how widely it gets adopted.
Lantern to me doesn't feel head and shoulders above the other options, just a nice tool in the toolbox alongside Crypt, Relic, etc.
