I have only one card like that, not very noticeable in my opinion. What I do notice is the reviews online, everybody has deck seals, and none of my decks have a deck seal.
Were yours from the first or second run? I ordered mine from the first run (the first release date). Possibly the second run went smoother? =/I also ordered some decks, however none of my decks have seals and the card with the D&D logo has a border around it. Also the court cards have a wider border around them, but its not very noticeable. Aside from that the cards are great and I have noticedd no problems with the back design border or the 7 of clubs. Maybe the decks with seals and the decks without seals were two different runs.

How many decks were printed all together?
