It's random, All the dust cards are mixed up into one deck each(this removes the purpose of going to a different deck to use a card).

This makes the user a bit unpredictable because, it's like a guessing game. Since you won't know what card will be thrown next and what type of dust it will be, it will cause the opponent to sooner or later fall under pressure
