In yesterday's article of Making Magic by Mark Rosewater, he revealed the art of the card submitted by the Magic Invitational Winner, Antoine Ruel. As quoted from his article:

We were forced to move it off to the next large set. Along the way, it went through a few changes. You'll have to wait until the card becomes public to see what those changes are, but as a little teaser, let me show off the art from the card."
The card is named Ranger of Eos and here is the art:
