Magic the Gathering's September 2011 large set, Innistrad contains 264 cards. This makes it one of the largest of the large sets in recent history. The Innistrad set begins a story of dark gothic horror with tribes of ghosts, zombies, werewolves, and humans all pitted against each other in the plane. One of the newest mechanics introduced in this set is that of the "flip card" which utilizes the Transform mechanic. When certain conditions are met you literally turn the card over and it becomes a completely different card with seperate stats, abilities, and even color.
Each Innistrad booster contains 15 cards. Look for these great cards and others like them:
Garruk Relentless/Garruk the Veil Cursed, Geist of Saint Traft, Liliana of the Veil, Olivia Voldaren, Past in Flames, Skaab Ruinator, Champion of the Parish, Hinterland Harbor, Isolated Chapel, and the covetted Snapcaster Mage.
