The original Core Set Cube debuted on Magic Online just two years ago, and since then, we've had two new sets of cards with which to upgrade it. I have also added in some old core set powerhouses that were absent from the last version so you can try new strategies. Overall, about a third of the cube is different, so you are in for a fresh experience.

You can draft the new Core Set Cube from November 25 to December 2.
