Boosters are designed for players who can already build their own deck. They contain randomly assorted cards that offer players brand-new deck-building and strategy options. Boosters hide cards you won't find in preconstructed decks. You might even pull special metallic cards. The war is over. Mirrodin is now New Phyrexia. But the fight is far from finished! A New Phyrexia booster contains ten common cards, three uncommons, one rare, one basic land card, plus a token, poison counter, or rules card. In one out of every eight boosters, you have a chance to find a mythic rare instead of a rare card.
