As regards pricing, what the project costs is the producer's problem not the backers'.
If the producer ends up with a price which is competitive with the pricing of comparable decks on Kickstarter, it will be of no concern to most backers how much profit the producer is making for himself (or not making for himself).
If the price is much lower than comparable decks, astute backers will be concerned that the producer hasn't done his homework, will eventually realize that he is going to lose money, and will abandon the project.
If the price is significantly higher than comparable decks, then potential backers will take their money somewhere else. There are plenty of Kickstarter decks, and most collectors are not so obsessive that they have to collect every deck. Their money will go further backing other decks. The few collectors who are obsessive, and loaded with money, won't suffice to fund the project -- and anyway, even obsessive people can be aggravated by an unreasonably high price.
So, my advice to this producer would be: set the pricing to be like the pricing of all the other successful Kickstarter projects. If that means you can't do the project, then don't. Probably you will be forced to take this advice in the end whether you want to or not, because the project won't fund if you don't.
But there's a flaw in this. There are cases where a producer can indeed produce a deck for a much lower price. When purchasing decks in larger amount, for example, the per-deck costs drop, allowing the producer to charge a lower price, perhaps even below the typical market price for a deck. And what exactly would that typical market price be in the first place? Different decks have different costs associated with their production because of things like the features of the deck itself or the costs of shipping (if they're still included, since now many projects don't include shipping). There'd be no way to compare something like the NOC deck or the Silver edition of the 52 Plus Joker Club deck or the Stranger and Stranger Ultimate deck, if they were offered on Kickstarter.
While it sounds nice on the surface, the suggestion you gave oversimplifies the problem of deck pricing.
Your points are valid, but they don't really contradict my main point. Unless backers have unlimited funds and unlimited obsession to collect every KS deck, they will tend to allocate the funds they have for buying decks rationally. A deck which is lot more expensive than comparable decks will need to be "more better" (as my son said at 3) than the other decks on some dimension: superior art, a more well-known artist, a more limited run, shiny embossing on the tuck box, holograms, whatever. A producer can come up with any story he likes as to why he needs to price his deck higher, but even if the story is true, it isn't relevant, except to satisfy himself and the Internet that he is a nice guy.. Nice guy or not, In the end the backers will purchase the decks that provide the best price/performance.
A deck by an artist with no better a track record than the others, or with a print run which is not more limited, or which has no special "features' needs to be around the same price as the others, too. If it is the first time out by the artist, less limited, or with a printer thought to be inferior, the deck needs to be cheaper than the others. Or you better hope that backers of Kickstarter deck projects aren't rational.
