If your opponent's monsters on the field outnumber your non-Token monsters on the field: Tribute any number of "Mecha Phantom Beast Tokens"; Special Summon an equal number of "Mecha Phantom Beast" monsters from your Deck. Shuffle them into the Deck during the End Phase. You can only activate 1 "Scramble!! Scramble!!" per turn.
