For the multi tower, 5 different people must run the tower. Agree among yourselves who will be duelist number 1 (the easiest), through duelist number five (the hardest). Duelists can switch spots, if 2 people from the same tower duel each other in a placement duel. In a placement duel, if the person ranked lower on the tower beats the person higher than them in a match duel, they switch places. You can only challenge the person one level ahead of you, and both must duel with the decks that they use in the tower. In your post, you must tell who the 5 duelists of the tower are, and what decks they are using. You get 150 BP for beating all five duelists in a multi tower.
