so anyways, Bassically you want min 4 people. Obviously make an order of who gets what achievements To advance first you need 2 wins. this will put you in the Tower once your in the tower you cannot VS. anyone from round 1 or 2 so you need to send a second person up to round 3. the fastest way to do fights is once you match up against each other have 1 person quit the other person then gets a win almost instantly

and the faster the better i say lol. Once you start getting wins in the Tower you onry need 3 wins (up to match 5) then you'll get the achievement, now to save time the person who just got the achievement will be given the option "play king of the tower" select yes and then just wait until you move the next person into the Tower. After getting the achievement your still in the tower so it saves you a couple rounds really.
