Hi,

There are two promo cards from Magic 2015 Duels of the Planeswalkers that were given out to people who purchased the video game. They are alternate art, foiled versions of these cards:
Soul of Ravnica
Soul of Zendikar

The promotional booster packs also contain an insert. I've attached a scan of the front and back for reference. I'm not sure if this insert is specific to these promo boosters or not, although in the past the inserts have been.
