Dot.hack enemies has a way to set cards, and sometimes what you set can determine later in the game the outcome of the battle, especially if your opponent benefits from your set cards, or you benefit from set cards due to their skills activating on certain actions, or you able to summon monsters that require a number of sets to be played first... The fun part is, you can basically set ANY card in your deck... :-P
