The format is Modified limited.
Each player receives 1 Prerelease Deck Box, which will contain the following:
– 22 card evolution pack featuring key cards from current and prior sets
– 4 Sun & Moon Burning Shadows Booster Packs
– 1 of 4 alternate art promo cards
– 1 Deck building tip sheet
Players will open the 4 booster packs and, along with the 22 card evolution pack, build a 40 card deck with a 30 minute time limit.
Basic energy cards are supplied separately and should be returned at the end of the tournament.
You may use only the Pokemon and trainers/supporters in the prerelease deck box that you open. No trading until after the tournament. One difference is that if you have more than four of a card you can put them all in your deck if you wish. After the players deck is built a tournament is played using the decks, with 4 prize cards and a 20 minute time limit.
