There are 46 themes that range from the familiar to the curious. Common themes are each represented four times in different variations among the 121 packs, rare themes twice, and mythic themes are represented only once. The rarity of a given pack should not be taken as an indication of power level; but rather how replayable the theme is. The variant decklists of a given theme always have the same general flavor, mana curve, and game plan. In addition to the Rainbow deck, each color features two mythic themes, three rare themes, and four common themes.
