Wizards of the Coast -- the company, not actual wizards -- has sent word that the previously revealed Magic: The Gathering - Duels of the Planeswalkers DLC
will hit Xbox Live Marketplace
on October 21 (next Wednesday, to be specific). The expansion will include three new decks, three new cards for each of the original decks, new co-op levels and three new challenge levels. The DLC also contains a new single-player campaign. Those who wish to partake of the expansion will have to summon 400 ($5).
