"Huge Revolution" is a series of 3 Normal Monsters ("Oppressed People", "People Running About" and "United Resistance") and the Trap Card "Huge Revolution". The idea of this series is having at least one of each of those monsters and then activating "Huge Revolution" to clear the opponent's field and hand. Story-wise, it's about a kingdom which oppressed their people so much that they were forced to revolt. It's part of a larger series called "Royal".
