Here’s some info about Planechase:

The Planechase plane cards introduce a groundbreaking new way to experience planeswalking. Through this innovative new kind of card, two or more players can battle each other across a variety of diverse worlds, each with its own unique effect on the game. These thrilling new conditions add a whole new layer of chaos, meaning the only thing you can count on is unpredictability.

• There will be four Planechase Game Packs released on September 4th, 2009: Elemental Thunder, Metallic Dreams, Strike Force, and Zombie Empire.

Each game pack will contain 10 all-new plane cards, a ready-to-play 60-card deck, a six-sided planar die and a Planechase strategy insert with multiplayer rules.

Each of the 60-card decks will include 8 rares, and will be composed of cards from throughout Magic‘s history – including a preview card from Zendikar.

The 10 oversized plane cards comprise a planar deck. They feature all-new artwork depicting some of the more exotic realms of the Magic multiverse.

Each of the cards in the 60-card decks will be black-bordered and tournament legal. This means that these cards are legal for use in any tournaments where the original printings are still legal.

The cost will be $20 or $17 for League members.  Prizes will be determined by participation.
