Shadow Era is a Magic/WoW style collectible trading card game on iPhone and iPad (universal app).
Start your campaign by choosing your Human Hero, and get a free starter deck. Battle with AI opponents or other players to earn more cards, try out new classes, and even play as one of the evil Shadow Heroes. Your progress and cards will be saved on the server and can be accessed from any device or play on the web right in your browser.
Of course, if you like the game you will have to buy new starters using in-app purchase.
