Battle Deck Arena - This deck is built around to counter and exploit the opponent's mistakes. From Arena 1 to Arena 5, most players make many mistakes. The most common mistake I saw when I tried the decks were opponents who were too offensive. This deck has lots of good defensive troops to stop you pushing your opponents and then take crown their tower in a nice counter attack. There is also a low elixir cost deck at 3, 6, a good thing for new players as well.More fully functional applications:Can be easily storedCan be used as backgroundCan be distributed to friendsCan be used for online / offlineDisplay with materialUpdate every day
