MAGIC: THE GATHERING
- All cards are allowed.
- All deck should have 60 cards.
- Each player must list a deck and a sideboard and sends to the organizer of the event 24 hours before the start of it. Each player is allowed to bring 15 cards (in addition to his main deck) to the game. These cards are referred to as the sideboard. Players are not required to have a sideboard; but, if a player does have one, it must be exactly 15 cards, no more, no less. After the first and second game of a match, each player is allowed to swap cards in their deck for cards in their sideboard (aka "sideboarding"). This is a 1-for-1 swap, so both the player's deck and sideboard must remain the same size (often 60, and exactly 15).
- One hour before the start of the tournament, the lists of decks and their sideboards will be posted on the topic of the tournament can be viewed by all.
