This document's aim is to give a brief view of the Tournament Rules' most useful portion, in order to have something to consult in case of lack of time and/or uncertainty. This document's target is the Floor Judge in need, so there have been few cuts regarding the deck check part. This document is unofficial and completely fanmade: use it as a brief reference but give always priority to official documents.

The rules here have been arbitrarily re-ordered to facilitate readability and to be ready to use.

701. Enforcement and Penalties - General

Philosophy and miscellaneous.

  • 701.1. Philosophy
    • 701.1.a. Errors are assumed to be committed unintentionally. If the judge believes it was intentional, it is cheating.
      • 701.1.a.1 Players attempting to abuse error remedies to receive advantages are cheating.
    • 701.1.c. Judges should not stop errors from occurring. Instead they deal with errors that have occurred.
    • 701.1.d. Judges should not intervene in games unless:
      • 701.1.d.1. They believe a violation has occurred.
      • 701.1.d.2. A player requested assistance.
      • 701.1.d.3. They observe a situation related to Unsporting Conduct.
    • 701.1.k. HJ and HJ only may issue penalties outside of these guidelines.

  • 701.4. Shuffling
    • 701.4.a. Some remedies require shuffling the randomized portion of the deck.
    • 701.4.b. Many cards recycle cards to the bottom of a deck. The judge should do what they can using information available from the game state and from the players to determine which portion of the deck is knowable by one or more players, and separate those before shuffling that deck.
  • 701.5. Rewinding
    • 701.5.a. Some remedies allow rewinding the game state in extreme circumstances, where leaving the game in its current state is substantially worse than rewinding.
    • 701.5.c. For rewinds more complicated than a simple rewind, only the HJ or designated AHJ may authorize rewinding in this way.
506. Triggered Abilities

We need this to go on.

  • 506.2. Players are not required to notify other players of triggered abilities when they are not the accountable player, but may if they wish.
  • 506.3.a. A trigger is considered forgotten once its point of observable impact has been reached and a new game action is taken without the accountable player acknowledging the trigger.
  • 506.3.c. For triggers that occur “At the start of each player’s first Beginning Phase”, the accountable player has the full duration of the turn in which the trigger occurs to acknowledge the trigger before it's considered forgotten, regardless of its observable impact (Example cards: Obelisk of Power and The Arena’s Greatest.).
