Sure, Tarot decks can be used in divination practices, but that's not all they're good for, as proven by The Red Opera, a new tarot deck of endless possibilities up on Kickstarter. It's a tarot deck. It's a magic item deck. It's a playing car deck. It's a character deck. It's an adventure deck. It's a back deck (ok, it's not one of those).

The campaign's more than 4x funded with 28 days left to go.
