One is a virtual recreation of a card game that has been made obsolete by its recently-released sequel, and the other is a tactical shooter spin-off released in 2006. These dramatically different games, Magic 2013 - Duels of the Planeswalkers and Rainbow Six: Vegas, will be available for free to Xbox Live Gold subscribers this September as part of Microsoft's ongoing Games With Gold promotion.

As Major Nelson points out, Magic 2013 is slated to appear on September 1. While the downloadable game normally features a $10 price tag, anyone with a valid Xbox Live Gold account will be able to grab Magic 2013 for free until September 15.

Then on September 16, Rainbow Six: Vegas will join the Games With Gold lineup. Unlike Magic 2013, Rainbow Six: Vegas debuted as a retail game, but it too will be available gratis to any Xbox Live Gold subscribers until the end of September.
