As I see it, it's pretty simple.

As far as needing USPC permission to claim a project will be printed with them, well - I've seen countless projects make that statement. Without a signed contract in place, it's a little harder for them to dictate such terms. After all, we say "deck designer", they say "potential customer", so they're not going to push too hard on the subject, unless the designer has no intent of printing with them at all. USPC will help with a little bit of the planning work needed before a KS launch in terms of supplying best practices documents and templates and such, but as was previously stated, they don't begin actually vetting a project until a contract is signed and funding is in place. It's not impossible that they'd reject a project for certain reasons, but I've never seen them go that far - the closest would be a non-KS project, the Karnival Inferno deck; the company forced a redesign of the artwork to remove some of what they perceived as the more "Satanic" elements and the Bicycle brand name was removed.
The Alice of Wonderland Play Cards Deck was given an ultimatum by USPCC ... either change the project "to eliminate every Wonderland element (no Hatter, no White Rabbit, no Alice of Wonderland title, no Cheshire Cat, etc)," or pound sand. According to the project creator, "I could not foresee the original printer changing their minds late in the project." Cartamundi looked at the same project and the same copyright issues and arrived at a different answer. The project switched to Cartamundi. (Sadly, the project then ran afoul of money/shipping issues and deliveries are supremely delayed--but that's a rant for another day. :-)

BTW, I'm not saying that the printer is the judge and jury--they don't have the *final* say on whether you will get sued into submission by Disney's Army Men of lawyers. Or whether you would ever win in a court of law if you *did* decide to play
How Big Is Your Budget For Lawyers? with someone like Disney. But the printers are an absolute hurdle. If you can't convince them, then your project is done-zo.
Yes, done-zo is a legal term. Look it up.

P.S. This is about the digression topic, not about Nat's card deck. Knowing him, I'm guessing he's done the homework and has at least lots of his non-infringing non-Disney ducks lined up already.
