Thorough Investigation Rulings

  • Jul 23, 2021

    A player may only have one dungeon in the command zone at a time.

  • Jul 23, 2021

    Choosing the dungeon or room to venture into is part of resolving the venture into the dungeon keyword action. Once that choice is made, players may not respond until after the appropriate room ability has triggered.

  • Jul 23, 2021

    Dungeon cards are not part of a player's deck or sideboard. In both constructed and limited formats, players can use any dungeon card when they venture into the dungeon.

  • Jul 23, 2021

    Dungeons are removed from the game as a state-based action.

  • Jul 23, 2021

    If you somehow venture into the dungeon while a room's ability is on the stack, you will continue on in the dungeon. If you're already in the last room, complete that dungeon and start a new one.
