Wednesday and Friday
And Saturday morning! :-) Wednesday, Friday - 530pm, free to play, winner gets a free pack! Usually 20+ players. Saturday - 1130am, free to play, winner gets a free pack! Usually 30-40 players!
To be honest, I am sure if you came in anytime there would be people with commander decks ready to jam. But I would recommend Friday night and Saturday afternoon as the best times.
