If you keep many hands that do not contain the card, it is probably not fundamental to you functioning
Elspeth, Suns Champion for instance would definitely get points for Standard dominance during her time there, but would not be considered a Modern staple despite seeing occasional play in that format
Some hobbyists note slight variations between production runs across different years, which might matter if you are trying to make thousands of cards look completely identical
