In order to get this to the most people, I've decided to put this up on my RSS feed as well as send it to the boss at Cardshark.  Inside you'll find anything you could ever want to know about going to the Prerelease.  Included are tips for preparation, getting there, surviving once you get there, and actually playing.  There's a quick tutorial on building your deck with a focus on the new set.  I also give a rundown of mechanics new and old that will be in the set, along with a few tips for each one.  I hope this is some help to you.  Stay tuned for a new episode of The Mana Pool coming soon!
