The NSFW cards will be variant cards of a regular card; for example, we may choose to make NSFW versions of the Horsemen that will only be in the NSFW deck and will replace the regular versions in that deck.
Delay cards remain until the Horseman kills them, at which point they go into the discard stack. According to Mark, "The points are like hit points — if a card has a resistance of 3 vs Death, then Death with an attack value of 2 can't kill off that card until he gets his Horse, also a value of 2, giving Death an attack of 4."
Mark says that just one deck is needed to accommodate up to four players. Extra decks would extend the game time, as long as you remove the Horsemen cards (OR I suppose you could increase the complexity by making players fight off as many as eight Horsemen — though that has not been tried yet in playtesting).
We're in very early development, so NSFW cards have not been created yet. They will be lewd, some will feature nudity, and if you've read a Mark Lawrence novel, well then, you should know what to expect.
