The Into the Darkness expansion for Duels of the Planeswalkers 2012 is a must own for anyone who plays the base game. The additional decks, cards, and modes are all welcome additions to the game and only add to an already addictive base-game. The ability to play as the Archenemy in particular is something that is worth the price of admission alone although it makes you wonder why it wasn't the ability wasn't included in the base game back in June.
