So, I haven't played since around Fallen Empires in the 90s, and I find myself registered for the prerelease tourney on Saturday.  Help? So, I haven't played in going on 14 years now, and I pulled my cards out of storage this week to play with my son while he was at my house.  After a visit to the local store to check out the state of the art, I'm now booked into a tournament on Saturday.

What do I need to know?  I'm reviewing the set previews right now, but I have no idea if that's sufficient, or I'm missing anything large that has happened while I was married.

I'm Hunting down the official rule book.   I used to carry around a binder of errata and rulings -- is that still needed?
