MTR 4.2 Tournament Shortcuts

A tournament shortcut is an action taken by players to skip parts of the technical play sequence without explicitly announcing them. Tournament shortcuts are essential for the smooth play of a game, as they allow players to play in a clear fashion without getting bogged down in the minutiae of the rules.

Most tournament shortcuts involve skipping one or more priority passes to the mutual understanding of all players;

If a player wishes to demonstrate or use a new tournament shortcut entailing any number of priority passes, he or she must be clear where the game state will end up as part of the request.

A player may interrupt a tournament shortcut by explaining how he or she is deviating from it or at which point in the middle he or she wishes to take an action. A player may interrupt his or her own shortcut in this manner.

A player is not allowed to use a previously undeclared tournament shortcut, or to modify an in-use tournament shortcut without announcing the modification, in order to create ambiguity in the game.

A player may not request priority and take no action with it. If a player decides he or she does not wish to do anything, the request is nullified and priority is returned to the player that originally had it.

Certain conventional tournament shortcuts used in Magic are detailed below.

They define a default communication; if a player wishes to deviate from these, he or she should be explicit about doing so.

Note that some of these are exceptions to the policy above in that they do cause non-explicit priority passes.

  • If the active player passes priority with an empty stack during their first main phase, the non-active player is assumed to be acting in beginning of combat

    unless they are affecting whether a beginning of combat ability triggers.

    However, if the non-active player takes no action, the active player has priority at the beginning of combat.

    Beginning of combat triggered abilities (even ones that target) may be announced after any non-active player action has resolved.
  • If the active player passes priority with an empty stack during their second main phase, or uses a phrase such as “Go” or “Your Turn” at any time, the non-active player is assumed to be acting in the end step unless they are affecting how or whether an end of turn ability triggers.

    End of turn triggered abilities that do not target resolve after the non-active player passes priority.
  • Whenever a player adds an object to the stack, he or she is assumed to be passing priority unless he or she explicitly announces that he or she intends to retain it. If he or she adds a group of objects to the stack without explicitly retaining priority and a player wishes to take an action at a point in the middle, the actions should be reversed up to that point.
  • If a player casts a spell or activates an ability with X in its mana cost without specifying the value of X, it is assumed to be for all mana currently available in his or her pool.
  • If a player casts a spell or activates an ability and announces choices for it that are not normally made until resolution, the player must adhere to those choices unless an opponent responds to that spell or ability. If an opponent inquires about choices made during resolution, that player is assumed to be passing priority and allowing that spell or ability to resolve.
  • A player is assumed to have paid any cost of 0 unless he or she announces otherwise.
  • A player who casts a spell or activates an ability that targets an object on the stack is assumed to target the legal target closest to the top of the stack unless the player specifies otherwise.
  • A player is assumed to be attacking another player with his or her creatures and not any planeswalkers that player may control unless the attacking player specifies otherwise.
  • A player who chooses a planeswalker as the target of a spell or ability that would deal damage is assumed to be targeting the planeswalker’s controller and redirecting the damage on resolution. The player must adhere to that choice unless an opponent responds.
  • A player who does not scry (or look at the top card of the library after taking a mulligan) when
    instructed to is assumed to have not looked and chosen to leave the cards in the same order.
  • In the Two-Headed Giant format, attacking creatures are assumed to be assigning combat damage to the defending team’s primary head, unless the creature’s controller specifies otherwise.
