Duel Decks: Garruk vs. Liliana is the fourth set in the Duel Decks series. It was released on October 30, 2009, with an MSRP of US$19.99. The decks were reprinted with new card frames in December 2014 for Duel Decks Anthology.
Garruk vs. Liliana contains two preconstructed theme decks, one centered around Garruk Wildspeaker and the other around Liliana Vess. Like Jace vs. Chandra, Garruk vs. Liliana depicts the rivalry of two planeswalkers and is a set of largely flavor-based theme decks.
Garruk vs. Liliana features two cards with alternate art and holographic foil treatment; Garruk Wildspeaker and Liliana Vess. Furthermore, the set includes another four cards with alternate art; Blastoderm, Harmonize, Mutilate and Snuff Out.
