Team Constructed Events
Team Constructed is a Magic: The Gathering tournament format in which each member of a three-player team competes using a single Standard, Pioneer, and Modern deck. Teams must present three format-legal decks. Unified construction rules do not apply. The same card may appear in multiple decks (e.g. four  copies of Hallowed Fountain in a team's Pioneer deck and three  copies in its Modern deck). Deckbuilding rules for individual formats still apply.
Players on each team are seated as follows: Seat A is Modern, Seat B is Pioneer, and Seat C is Standard. Each player plays a best-two-out-of-three games match where Competitive REL rules apply. The first team to win two (2) matches wins the round, and their team earns three (3) match points.
Teammates may communicate with each other about gameplay decisions such as mulligans, sideboarding, and in-game actions; however, slow play penalties still apply (MTR, Section 5.5). If a player wishes to leave the table during a match for any reason, that player must call for a judge first or they will no longer be allowed to communicate with their teammates.
