Mirrodin is the next standalone set after the Onslaught block and is the first set to contain 306 cards instead of the previous 350. The two expansions (Darksteel and Fifth Dawn) will each contain 165 cards (instead of the previous 143).

The Mirrodin expansion includes randomly inserted foil-finished premium cards in a limited, 306 all-new, black-bordered card set featuring the new card face introduced in the Core Set - Eighth Edition. Mirrodin features a brand new story line and will take place in a new setting for Magic (in what appears to be a dark, almost futuristic world).

Mirrodin offers you an artifact rich environment never seen before in the game of Magic. With 306 black bordered cards featuring the new card design, the set challenges you to arm yourself with the first new card type since Legends - equipment cards. Unlike enchantments, when an equipment card is attached to a creature, it can "fall" back into play even if the creature is destroyed and then be re-equipped onto another creature.

In addition, Mirrodin marks the beginning of a new story with new characters. Glissa Sunseeker, the finest hunter and perhaps the most skilled warrior of the elves, begins her story to find out why the monstrous "levelers" seek to destroy her. It is this search for answers that will begin to uncover the mysteries within Mirrodin. So get set for a grand new world filled with amazing imagery and a fresh new look.
