That's Elspeth! She will be our third exclusive Magic pin available to the PAX crowds. To get her, you'll need to come by the Magic: The Gathering booth and demo Magic 2014—Duels of the Planeswalkers. She's only available while supplies last!
We'll have more information soon about what's happening at PAX and what you need to know about attending our PAX Event—something we've done every year, growing it into one of the awesome events of every year's PAX.
