I just saw that this image was released a few weeks ago. It's called Timetwister. It's an alternate take on the art for the classic Magic card of the same name. It will not illustrate an actual card, but, like Force of Will last year, the original painting will be given as a prize. In this case, the winner of this year's Legacy World Championship at GenCon in August.
It's oils on paper mounted to MDF, 13" x 17" if I remember correctly.
