Sakura has all of the cards and Yoh has his sword and Amidamaru in his third form.
i mean like if it takes an incantation or something. cuz yoh is pretty fast. if its not instantanious, then im gonna give it to yoh via speedblitz. if it IS instantanious, then i'll give it to her. if thats the case then it should be restricted for a more fair match IMO.
