Don, to answer the question, the White Lions series B decks (at least the ones I used) were traditionally cut, as were the Silver Split spades. That's one of the reasons why Blaine decks were one of my go-to decks for practising with, before EPCC and LPCC started business.
In response to a question I posted in one of his KickStarter campaigns, Erik Mana also confirmed that even if you ask USPCC for your deck to be traditionally cut, every single deck won't be guaranteed to have the requested/demanded cut.
I think I've tested pretty much every single marked deck that's released in the past 4 years -- because card cheating/crooked gambling is what got me into cards in the first place, and so I marked decks do intruigue me.
The UMD deck is terrible. I was going to start putting it through the riffle test, but before I even started, I saw the blatant marking in the top corner. Wasn't impressed at all.
The Bicycle 1800 marked deck isn't bad, but it doesn't pass the riffle test -- that's how I found the markings, because I couldn't find the instructions video anywhere. As the 1800 design deliberately has different wears and tear patterns across different card backs, the markings are definitely better hidden than 90% of other marked decks... but as the markings are in "the usual place", after a few riffle tests, you can see them. It took me four riffles. Not bad.
The Madison Dealers fail the riffle test quite blatantly. Yeah, it does require one to figure out the dot code, but it's not difficult.
The Black and White Lions marking system is much better than the Madison Dealers, because although the Lions do also have a pattern type of code, even though they fail the riffle test, like the Bicycle 1800, the riffle test failure is difficult to detect, because the offsetting of the pattern is probably by only a couple of pixels.
The Sharps are the only marked (or rather, readable-via-back-design) deck that I know of. I trust that you know about "juiced" decks that cheaters use... that's what the Sharps use.
As per LPCC's Instagram account, they're producing a second edition of the Sharps. For me, that's probably the best news I've heard in months. I'm curious to see whether they really can top the first edition!
In the interim, for those who don't have the Sharps, the DB Lions decks are a decent alternative... if you don't mind the furry edges!
