Game Traders Galleria will be having its first free Commander event this Thursday, the 22nd of November starting at around 6:30pm. The aim is to run this fortnightly, so turn up with your EDH deck for some good times and, perhaps, some awesome cards to add to your deck. Or you could turn up anyway and learn the format. There are volunteers who will be happy to teach you the ins and outs.
If you have any queries, feel free to email firstname.lastname@example.org
or ask through their Facebook page, which is linked below.
