It's a Bicycle deck, images of the skeletal court cards are easy to find, so you should mostly know
what you are getting without a review. Worth noting is that the face cards are standard, with a
small center pip for the ace of spades (instead of the normal large Bicycle ace of spades design, or
a custom design like most custom decks). Also, that Grimoire/Mandolin double back is a red Mandolin
back, if you need to match it for an effect. The BigBlindMedia Karnival line is hard to compete
against as far as skulls per capita, but if you're into that kind of thing, it's an attractive deck.
(The usual caveats about custom decks and character apply of course.)
