Including the namesake Planeswalker cards is a long overdue move that will be well received.
The feature list from the press release is much more forthcoming: Not a lot of info there beyond that the base game is structured around the upcoming Summer set of the physical game, Magic: Origins. The former is what made it so popular, while the latter drove people off from last year's edition. Which way will the newly announced Magic Duels: Origins point me? It marks a switch from a yearly release structure to a free to play, updated regularly one. The first game in the Duels of the Planeswalkers series is what got me into it, while the last nearly got me out with its terribly designed interface, boring grind of unlocks and poorly thought out battles. Ah, Magic, my particular brand of cardboard narcotic.
