This is the challenge tower. Here you can create a tower, by yourself, or with a team. A tower has exactly 5 levels. Level 1 is the easiest, and level 5 is the hardest. You must make the decks known in your topic of your tower. Each level is a match duel. You do not have to duel all 5 levels consecutively, you can challenge one a day if you want to. You only get BP the first time you beat the tower. I hope you like this!
