I have a pretty long wishlist in standard (plus some EDH stuff).

I value the foil at about $40 in a 1:1 trade (http://ark42.com/mtg/pricehistory.php?s=Return+to+Ravnica&c=Hallowed+Fountain&f=1).

** UPDATE **
The card has been traded. Thank you for your interest.

Apparently I have everything that you need, and I'm also from Minnesota. So you should probably trade with me :D I'll send you a trade!

I've received a number of offers and will review them this evening. Thank you for your interest.
