Is there duping and cheating in EP3?

yeah, i just bearly beat this team in a tourney, and they were using spamming decks and time was almost up and there was like 10 seconds left and they just said screw it and did useless commands cause they thought we couldnt get to them cause of there was a wall of monsters between us and them and we just bearly won and they were like omg how could this happen thats probally my most memorable victory in ep3
