The first ever Vintage Unleashed event is being held online in the Team Serious Virtual realm. This is an open event, free to play, playtest cards allowed (or play on Cockatrice or MWS or whatever). Connections and player pairings are made through Discord.
Date: July 11, 2020
Time: Noon ET
Location: Team Serious Virtual Realm (Discord)
Vintage Unleashed is a player-created Vintage format that opens the restricted list greatly, so there are more exciting cards and interactions. Complete rules and restricted list are available, and you can learn more about the format from Joe Dyer, Vintage 101 and Serious Vintage. Very fun format, still very open. I guarantee if you look at the restricted list and come up with the "best deck" you probably haven't.
