undefined [LON-068] - Labyrinth of Nightmare Unlimited - Common

This card can only be Special Summoned by removing 1 WATER monster in your Graveyard from play. As long as this monster remains face-up on the field, during each of your opponent's Standby Phases, you can change the battle position of 1 of your opponent's face-up Monster Cards. Once changed, the monster must remain in this position for the rest of the turn.
