I've been thinking a while about this, and I think it would be awesome if you made physical cards or card packs that you could buy. Also if you included barcodes or some other scannable code that would allow you to scan it into your virtual deck would be a sweet addition to it. Even without that, I would love to get my hands on a collection of real phone destroyer cards like Cyborg Kenny, Awesome-o, Pirate Butters etc.
