This is actually old news, but today
the previews on the official site begun, so that's why I'm bringing this up. Why should this interest you? I know most of you started playing M:TG way back (and stopped playing way back as well), and this set is (probably) especially for you: the sequel to Alliances, the last part of the Ice Age block. This means a story line that is familiar, and snow-covered lands! Boo-yah!
P.S. Did I mention I now have a Tombstone stairwell deck on Magic Online? No?
