September 19-25: Prerelease Week!
We're not saying this just to encourage you to go to the Zendikar prerelease (although it is this weekend, you know). But just look at how many prereleases have taken place over this weekend in September!
September 21, 1996: Mirage Prerelease
September 25, 1999: Mercadian Masques Prerelease
September 23, 2000: Invasion Prerelease
September 22, 2001: Odyssey Prerelease
September 20, 2003: Mirrodin Prerelease
September 19, 2004: Champions of Kamigawa Prerelease
September 24, 2005: Ravnica: City of Guilds Prerelease
September 23, 2006: Time Spiral Prerelease
So this is essentially the week where a huge chunk of Magic was seen for the first time. Surely you can forgive us for mentioning the Zendikar Prerelease this weekend just one more time?
