Very curious if anyone else has noticed that their Stronghold cards have a underlying blue around the back side border of the card. Was just making sure a Sliver Queen was authentic and noticed this for the first time. Got out my Volrath's, Diamond, and Ensnaring Bridge and low and behold.... blue ink (Could be blue paper) under the back border. Something else I noticed was there is more blue to them as well on the light test. Basically no blue on a Sliver Queen, yet a lot of blue tint comes through when shinning a light under it. Don't own any other Stronghold cards to my knowledge, so I can't further test this finding. Can someone confirm please? I'll try and attach a picture.
