Are not on this site. But I heard they’re starting on the “mother ship” (Wizard’s main MTG site, if you haven’t heard that term before) tomorrow….which means at 12:01am (22 mins from the time this was written) we get to see new cards woooooooooooooooooooo! Gentlemen (and ladies!), start your rapid browser refreshing at 11:59!
http://www.wizards.com/Magic/Magazine/Default.aspx is the site. It has new articles and random decks and announcements every weekday, so check it out if you aren’t already obsessively checking it every night at midnight like I do.
