It is my understanding (and I may be wrong on this) but the way a lot of cards are written (ie. may be used twice during battle, or the site that says return this card from battle) makes it sound like when the Hero or Evil Character enters battle, the card holder chooses to bring those cards into battle with them. That means when they enter, those cards are placed in the field of battle next to the controller. This would make a new twist to the game as per the fact that if a card shuffles all cards in battle, those cards would go also. When the Lost Souls card is shuffled after a rescue, it resets. This means Thirty Pieces Of Silver or Jephthah (J) could also reset. I really think this should be explored more fervently.
