Immovable Rod

To venture into the dungeon, a player moves their venture marker into the next room of the dungeon they are currently in. If they aren't currently in a dungeon, that player instead chooses a dungeon card from outside the game, puts it into the command zone, and moves their venture marker onto the first room.

Some abilities still work even if they have been removed. Specifically, static abilities that change an object's types or change an object's colors will still apply even if those abilities are lost.

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

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.

Once you resolve the last room ability of a dungeon, that dungeon is now completed and is removed from the game.

If a creature has a characteristic-defining ability that sets its power and/or toughness loses that ability, the power and/or toughness (as appropriate) become 0.

The player venturing into the dungeon chooses which dungeon they will venture into. They may choose a dungeon that they have already completed this game.

You can only move forward (well, downward) in a dungeon, never backwards or sideways.

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