Blue Heart

why does my magic the gathering card have a blue heart stamp with stars in it on it?

i have a dust of moments card with a little blue heart stamp with stars in it. this has peaked my interest.

It most likely means that it was drafted during a professional event such as a pro tour. They put stamps on the cards the players have drafted to make sure they are not cheating. Kind of hard to find.
