All the rules for individual Limited tournaments (Section 7) apply to Team Sealed Deck tournaments except as follows.
Each team must receive the same product mix. For example, if one team receives twelve Zendikar Rising draft boosters, every team must receive twelve Zendikar draft boosters.
Eight draft boosters per team are recommended for two-person team tournaments, and twelve draft boosters per team for three-person team tournaments. For the recommended product mix for the current block, refer to Appendix D.
All cards must be assigned to a player’s deck or sideboard during deck construction and cannot be transferred to another player during that tournament. (Players do not share main deck or sideboard cards.) Players may exchange cards in their pool in Regular Rules Enforcement Level tournaments that do not use decklists, but only between rounds.
