Ok on August 4th 2001 I notice something wierd and puzzleing so I made a hipothesis. that when the book changed it's seal. When someone is the master of the cards the book will also become in there controle so it barred her name till the next captor. Now onto the Wand the week before I noticed that the card would work still on the cards I guss it has to set in for a while that was what confused we. But the next week on the 4th the wand wouldn't work. I gess it would work on the old cards for one last time. I aso noticed on the 4th that the cards drew there energy from Sakura to change form. I gess one more thing she had to learn ne audintations to get the wand to work.
