8.5 Unified Deck Construction Rules

Team Constructed tournaments use Unified Deck Construction rules: With the exception of cards with the Basic supertype or cards with text that specifies otherwise, a team’s combined decks may not contain more than four of any individual card, counted by its English card title. (For example, if one player is using four copies of Naturalize in a Multiplayer Constructed tournament, no other player on that team may have a Naturalize in his or her deck.) If a card is restricted in a particular format, no more than one of that card may be used by the team. No players may use cards that are banned in a particular format.

Unified Deck Construction rules are only applied when all members of a team have decks of the same format.

Vale in tutti i tornei a squadre in cui si gioca lo stesso formato:

kalle, io questa regola non l'ho mai vista applicare ai tornei team vintage.
Altrimenti un solo mazzo sarebbe spoilerato
