Basically, Rogue Decks are unexpected decks that will be seen around the tourney area. Due to this, a Rogue deck will have the Element of surprise to Trick and terminate your opponent with many not popular Cards.
Having lotsa different Techs also makes a rogue deck different from any other decks. Other than that, the word "lock" and "abuse" are really well, abused. Lock uses different and disruptive Trainers to lock and/or stall your opponent while you attack at the same time, leaving you with an easy win, if it is sucessful. Abuse is mainly about maxing a card in the deck and use its power or effect throughtout the game.
Well, that's all I can say.
