There was cool art and two new Dragon's Maze spoilers revealed at PAX East in Boston this past weekend. 

Here are the spoilers, both available for preorder:

StarCityGames.com is also preselling all ten Guildgates from Dragon's Maze. The Guildgates will have different art and Dragon's Maze expansion symbols. Each booster pack of Dragon's Maze will contain, instead of a basic land, a common Guildgate, a rare shockland at rare, or a mythic Maze's End.

More artwork was uploaded to the Magic: The Gathering Facebook page here.

The Prerelease for Dragon's Maze will feature a maze poster, and the guilds will compete to see who can get through the maze first. At the Prerelease, you'll be able to pick any of the ten guilds and receive a "secret ally" or a guild pack from a set in an ally color. Dragon's Maze Sealed is more designed as a three-color format, according to the Magic panel at PAX East.
