Duels of the Planeswalkers is an interesting game (that I should probably review, though I feel like a lot of people already bought it) but the best aspect are the promo cards! For those of you with the full game, go to “Player Account” then “Promotional Unlocks” which will allow you to “Enter Codes.” Once you open that entry field, you can enter the following codes to unlock a new card for each of the ten decks!

KWPMZW
MWTMJP
WMKFGC
NCTFJN
GDZDJC
HTRNPW
FXGJDW
PCNKGR
GPCRSX
