Duels, practice and tournaments

I think it could be a great idea to be able to test out your defenses in a practice mode. You could be able to select the kind of troops you want without affecting your ressources. Next thing is being able to have personnal tournaments between your clanmates. It could be an alternative for clans who don't like to war. the clan is divided into two even teams. In each team people will fight each other until there is only one standing, and then proceed to have the two champions fight for the title. clanmates also could be able to bid a limited amount of gold on who they think would come out champion, and then have the loot distributed evenly between the bidders who won. The duels are for players who want to have a 1v1 battle between your friends,or clanmates. Thanks for reading :)
