jay behrensI define a crease as a flaw in the card that breaks the original surface of the card causing loss of coloration and noticable defect. Something that doesn't break the surface I would call a wrinkle, I wouldn't grade anything with a wrinkle higher than EX, and personally would be preferable to a crease since it would leave the original picture in tact which is the most important thing for me.
