[Update: The likelihood of this rumor being true has dropped significantly, as this artwork was used for the Magic Online Cube. Thus it does not indicate a potential reprint in From The Vault: Twenty.]
According to the Original Magic Art blog, Winter Orb will be one of the cards included in the upcoming Magic collector's set From the Vault: Twenty.
Artist Brian Snoddy's art for the piece, seen in the Magic Online Holiday Cube, will reportedly be the art used in the new collector's set, slated for release August 23 of this year.
Winter Orb has never been printed in foil and is not on the Reserve List, making it an ideal candidate for the box set.
