Tournament matches will be played on Pokémon Showdown using the VGC 2009 ruleset.
VGC double battles require you to build a full team of 6 Pokémon but only bring 4 into each battle. You can change which 4 you bring into each battle for each game within a set.
Players are only allowed to bring one team of 6 for the entire bracket and are required to post their full team in this thread before their first match. These restrictions are keeping in line with how official VGC tournaments operate now.
VGC matches will be played in a “Best of 3” format where the winner will need to win 2 games to advance to the next round. The tournament will be a Double Elimination bracket, meaning players that lose in the winner’s bracket will still be able to progress through the loser’s bracket.
