It's minor enough to not bother about it. Pokemon / mtg / yu-gi-oh is where the games are at. They're smart to keep them to a standard size.
Then you also have a folder and storage box issue too.
BTW, check the curl on foil slammer.
I do have a positive comment, the art looks pretty good, but yea, without a viable storage solution it'll be hard to collect, which is a shame because people would collect these for the g1 style art.
