Worldwake is the next expansion to Magic: the Gathering. It is slated to be released on February 5th, 2010. Of course, with the release of this set, the sets for standard increases by one. With worldwake, the list of Standard competitive sets is: Conflux, Shards of Alara, Alara Reborn, M10, Zendikar, and Worldwake.
There is at least one new Planeswalker to be included in the set as well. Jace, the Mind Sculptor is a blue planeswalker and at first glance, powerful. Compared to the other Planeswalkers, Jace, the Mind Sculptor has an extra ability which is also unusual. For a +/-0, you get an opportunity to draw three cards and put two on the top or bottom of the library.
It is also very likely that within one week of release, many stores will be having prerelease events and I will be sure to keep you all posted on any more information that I get .
