During the tarot reading scene, Gadsen shuffles the cards. Gadsen has a ring on his left hand which is not shown during the close up of his hands.
The "tarot cards" are a deck of Italian playing cards, except for the Card of Death they are not a real Tarot deck.
After Willie haphazardly hammers out a hole in Thor Coffin's wine cellar, he covers it with a simulated brick facade that exactly matches the shape of the hole.
When Gadsen shuffled the deck of Tarot cards and gives it back to Barney, the camera clearly shows a ring on the left hand of Gadsen that was not there during the shuffle.
During the Tarot reading, Barney implies that the Death card literally means death, but in Tarot symbology it actually signifies change or transition, of which literal death is only one type.
