Bicycle decks are not super commonly knocked off. Why? If you successfully create a knockoff that looks good enough to sell, what do you make? $1-3, max. There is no major market for it. There are some overseas knockoffs, but you can usually tell. Misspelled words, poor design, etc.
If you are going to knock off a deck, you need to be able to make money. The decks that are most often knocked off are things like Jerry's Nuggets, where a single deck goes for several hundred dollars.
Why do they faro poorly? Most USPC printed decks are cut in such a way that the faro is not easily performed. There are many decks out there that are cut specifically so that you can faro easier. It has to do with the cut edge of the decks and the angles you get by cutting different ways. A faro is not something most decks were designed to do, though you can coax most decks into doing it with practice. Bicycle Standard are affordable, no-nonsense decks that have zero "features". They aren't going to have any sort of special stock or finish, no special cuts, no embossing, debossing, foil, etc on the tuck case, no custom faces, etc. Those as as plain of a decent quality deck as you will ever find.
