602.1. Sealed Deck

602.1.a. The rules for constructing a Riftbound deck are found in CR 101 Deck Construction, except where modified here below for the Sealed play format.
602.1.b. Sealed Deck is a limited format where players are provided with 6 unopened booster packs to construct their deck.
602.1.c. Main Decks in Sealed Deck are exactly 25 cards.
602.1.d. The domain identity of a limited deck is any three domains, or any domain plus the domains of its Champion Legend (if it has one).
602.1.d.1. A sealed deck may have any Champion Unit that is included in its domain identity as its Chosen Champion, even one that does not have a champion tag that matches its Champion Legend (if it has one).
602.1.d.2. A sealed deck may play any signature spells that are fully included in its domain identity, even if they do not include the corresponding champion.
602.1.e. A sealed deck is still legal if it has no Champion Legend or Chosen Champion.
602.1.e.1. A player may opt not to use a Champion Legend or a Chosen Champion in their sealed deck even if they opened one in their provided packs.
602.1.e.2. If a player's deck doesn't include both a Champion Legend and a Chosen Champion, they draw a card at the start of their first beginning phase each game. (If they have neither, they still only draw one card.)
602.1.f. In competitions where a sideboard is allowed, a limited deck’s sideboard is every card provided to the player as part of the competition that isn’t used in their deck construction, unless otherwise specified.
602.1.g. The normal limits on copies of named or signature cards do not apply.
602.1.h. Sealed decks must have at least three battlefields available, so if any are not included in the cards provided to the player as part of the competition, the player may use a blank battlefield represented by a facedown card.
602.1.i. Players may use the six basic Runes from any source for play in a limited competition, even if they were not in the cards provided to the player as part of the competition.

602.1.k. Players may not use electronic devices to take notes or as a strategic aide during sealed deck building.
