The new Seasons Seronda deck is my favorite.
It's a very nice deck, but it's not really borderless though. The borders are black.
In that case, neither are the Limited Edition 1 & 2 decks.
I guess we all have different believes of what borderless cards are. The reason why I mentioned the Limited Edition #2s is because the borders on the back are blue while the ones on the faces are white.
However for the Limited Editions #1, the borders on front and back are both white, and on the Seronda, they are both black.
OK, let's do this - let's define what "borderless backs" actually means.
One possible definition would be any deck that prints into the bleed. This would include all patterned backs that extend beyond the cut, but it would also include all the colored decks as well. Every black deck would be considered borderless.
My preferred definition is one that has a PATTERN that prints into the bleed. That sounds like more of a true definition, especially from a card mechanic's perspective. A black deck might not help a cheating gambler, while a deck with patterns going off the edge of the card would certainly help.
With that definition, there's fewer choices, but it's better defined.
Limited Ed. decks - no
any black deck with a black edge, regardless of front colors - no
any colored deck with a matching edge, regardless of front colors - no
Steamboats, Bee Diamond Backs, Vintage Plaids (and other cards using the same classic patterns) - YES
I consider Arcanes as bordered cards as well. The white ones have white faces and white borders, while the black ones have black faces and borders.
A borderless deck for me is when, if you put one card upside down in the deck, you won't be able to notice that card if you look at the sides of the deck. This is the case for both Arcanes, and Shadow Masters, etc.
Uh, Nathan? You just contradicted yourself. Arcanes can't be both bordered (as in your first paragraph) and borderless (as in your second paragraph).
BORDERLESS means the back DESIGN, and not simply the color, extends beyond the edge of the card and is printed into the bleed area surrounding the card.
