The new Garruk's Revenge expansion is now available on Steam with new content for Magic 2015 - Duels of the Planeswalkers, the virtual card-based strategy sequel. The expansion also represents a fundamental change to the game, as now all cards can be earned by playing. Here's word:

Garruk's Revenge puts the fate of Garruk Wildspeaker, the deadliest hunter in the Multiverse, in players' hands. With four new Campaign levels and an expanded Explore level, players take on the role of Garruk, using his deck to battle their way through challenging foes. With every victory, Garruk's deck strengthens, becoming more and more corrupt.

The Expansion features a collection of fan-favorite cards from the Shards of Alara block, which players unlock to later modify their own deck creations as they hunt their prey across the planes of the Multiverse.

Along with the release of Garruk's Revenge, all cards available to players in the original Magic 2015 campaign, Hunt Bigger Game, and the Expansion are now entirely earnable through gameplay.
