Configuration: 60 cards per deck.
Glissa, Bosh, and Slobad journey deep within Mirrodin's core to confront the insidious Memnarch. With them is the Kaldra avatar--an immensely powerful being of energy summoned when Kaldra's sword, shield, and helm were brought together. But what was supposed to be the world's salvation turns out to be a vile trick. With a single spell, Memnarch seizes the avatar and turns it on Glissa and her companions.
Kaldra's avatar relentlessly pursues Glissa into the Tangle, destroying everything in its way. Finally, at the Radix, Glissa's destiny becomes clear. As rage and despair overcome her, Glissa's body calls forth a great column of green mana from Mirrodin's core, annihilating the avatar in the process. Now that mana hangs overhead in a glowing sphere--the green sun at last, Mirrodin's fifth dawn.The Fifth Dawn set takes Mirrodin block out with a bang. Bigger creatures, better effects, faster equipment, and more reasons to play all five colors. Throw in cards that combine in ways guaranteed to wreck your opponent and you get a set you have to play to believe.
