It's gonna be quite easy. You get a partner with whom you'll go through the entire Tournament. Together, you'll have to beat other teams.
Now, how do you do this? Basically, each team consists of 2 people. Number 1 and Number 2. For example, me and Eros. I'll be number 1 and Eros is number 2. If we were to duel against another Team, say Alexis and Omega Shadow. Then both numbers 1 would duel each other, and both numbers 2 would duel each other. So, if Omega were 1 and Alexis 2. Then I'd be facing Omega, and Eros would face Alexis.
Then, you get the results of those matches. If my team won both matches, we win and we go on. If we lost both matches, Omega and Alexis would go on. If both teams would have won, then both winner will face each other in the last game. Whoever wins in that will proceed with his team mate to the next round. Though for some reason, it'll have to be rolled with a dice or flipped a coin over if the losers should duel each other or the winners. Imo, should just be the winners.
I hope that explains enough how this whole thing goes.
