Carnage Wurm is an uncommon creature card from the Magic 2012 set, identified by its unique ability to deal damage to opposing players and creatures when it enters the battlefield. With a current market value of $0.13, it has a modest presence in the trading card market, appealing to collectors and players alike for its thematic design and synergy with various strategies. The artwork, created by Dave Kendall, adds to its visual appeal within the set.
