Hussar
Legend
Last time I saw a Deck in my game I think 4 of 6 party members drew from it; the other two peered out from behind a hedge. (after which one of the PCs stole it from the party, left the party, took it to town, and sold it...)
Last time I saw one as a player the party was 9 or 10 strong and either everyone drew or only one did not, I forget which.
Lanefan
I have to admit, my experiences jive with Lanefan's here, quite possibly including peering from behind something thick and protective.

Even when I introduced a Bag of Beans with over 100 different effects, they spent significant time playing with it.
Kinda goes back to the whole, "Do you push the button" thing. IME, OF COURSE players push the big red button.
