- Dox Summoned this card, which turned the field into a Labyrinth. each monster can move one space for each of its level per turn.
- Labyrinth Wall changed the entire state of gameplay. Players would have to move their monsters through a maze (a monster could move a number of spaces equal to it's Level, also termed Power Level, each turn) to reach their opponent's Life Points. It did not seem to be a Monster Card, although it was represented as such.
