Primordial Hunger is a red-green deck built around devour, from Shards of Alara. Planechase was originally released in 2009. This deck was released in 2012. Planechase is a card game and a variant of Magic: The Gathering with an emphasis on multi-player games. The set utilizes new oversized Plane cards, cards that are based on various locations (Planes) within the Magic multiverse, to modify the rules of gameplay. To play a game of Planechase, each player needs his or her own planar deck, consisting of at least 10 different oversized cards. The players may also use a "shared planar deck," which requires ten cards per player. Players cannot use more than one plane with any given name. When the game begins, the player going first reveals the top of his or her planar deck (or the shared planar deck), which is the plane the game starts on. Each plane card has a name, a type, one ability that applies at all times (either to all players or to whoever is the turn player at the time), and one "Chaos" ability. Players also need a six-sided die, called the "planar die." Each Planechase preconstructed deck comes with a "planar die" that has four blank faces, one "Planeswalk" face with the "Planeswalker" symbol, and one "Chaos" face with its own symbol unique to Planechase. During a player's main phase, that player can roll the planar die, with three possible outcomes. A blank roll of the planar die does nothing. If "Chaos" is rolled, the "Chaos" ability of the current plane card triggers. If the "planeswalk" symbol is rolled, the player "planeswalks away" from the current plane (put it on the bottom of its owner's planar deck) and he or she reveals the top card of his or her planar deck, which becomes the new plane that has been "planeswalked to." A player can roll the planar die as many times as he or she likes, but successive rolls cost an additional one mana for each time the planar die has been rolled this turn. Other than the above, the normal rules of the game are followed, and Planechase can be adapted to any multiplayer variant. Planechase 2012 introduced the "phenomenon" card type. A player may have up to two different phenomenon cards in his or her planar deck, which cannot have the same name. When a player planeswalks to a phenomenon, he or she follows the instructions on the card, then immediately planeswalks away from it.
