They're what await players of Duels of the Planeswalkers 2013. When a player first launches the game (or goes into the Extras tab), they'll get their code.

Neat, right? And here are the other two cards, which are for XBOX and Steam/iPad users respectively.
This promotion runs through December 13, 2012 (while supplies last).
