	Constructed Decks

Constructed decks are built in the Deck Editor and are used to play in constructed format games. This format refers to play in which players construct decks with their own cards before beginning a game.

Deck-Size Limits
Constructed decks must contain a minimum of sixty cards. There is no maximum deck size. If a player wishes to use a sideboard, it must contain exactly fifteen cards.

With the exception of basic lands (plains, island, swamp, mountain, and forest), a player's deck and sideboard combined may not contain more than four of any individual card, counted by its English card title equivalent

Sideboard Use
Players cannot look at their sideboards during a game. Before the beginning of the second or subsequent game in a match, players may change the composition of their constructed decks by exchanging cards from their decks for cards in their sideboards. Any card exchanges between decks and sideboards must be made on a one-for-one basis to ensure that the sideboard remains at exactly fifteen cards at all times. There are no restrictions on the number of cards a player may exchange this way as long as one card from the deck is traded for one in the sideboard.

The deck and sideboard will automatically be returned to their original compositions before the first game of each match. Thus, cards transferred from a player's deck to his or her sideboard, and vice versa, will be returned before the player begins a new match.
