For you people who have multiple decks of the same type for different purposes, example 3 celestian decks one for minions/boss killing, one for 1v1 and another for multi player pvp. You could label them 1, 2 and 3 ect. So you dont just click on one and find out its you 1v1 deck and you are starting a 4v4. This is a pain if you forget to check what deck it is until you are transported to the arena.
