There’s a new feature in the Magic the Gathering Duels of the Planeswalkers interface on the Xbox Live Arcade version.
When you go to Edit your Deck, you can now purchase ‘Keys’ to unlock all the cards or convert the uncommons, rares and platinums to Foil versions. I wouldn’t recommend using the keys to unlock all the cards because if you will be get them as you play, but using it to convert them to foil is a nice and refreshing touch. Unfortunately, this change is permanent.
To purchase a key, simply follow the onscreen instructions when prompted. The keys come with a cost thought, at 80 MS points, it’s pretty decent. I only spent it on one deck though.
