HoloGrid: Monster Battle is a symbiotic combination of physical components (two decks of 36 cards and two device stands) and a mobile app that uses the camera on a tablet device to render the cards as monsters. It's very much in the style of the chess-like game that one can see played by R2-D2 and Chewbacca during the original Star Wars movie.
This is not a card game that happens to be playable in an AR fashion, but rather a video game that employs a physical CCG to build your monster teams.
