Digital cards and physical cards differ vastly. Playing in the campaign is completely unfair as the AI can cheat and use more than the limit of 3 of the same card in a deck. The app is difficult to enjoy because of the lag and frequent "match cancelled" messages whenever you find a match in versus mode. This app would greatly benefit if it had a separate unranked mode were you could use the physical real life cards with their original effects and not the digital erratas.
