I haven’t been buying sealed product since WOTC sent the Pikertons to that one guy. But I am lately just Commander only, and my local shop has a biweekly tournament and I came in 4th place in the 1st of 6 rounds for a prize pool.
I at least came above the guy I dislike the most.
Team Fortress 2, with over 2100 hours logged. More back on the Xbox 360 copy and when it was free during the Mac Update.
