78 cards
22 Major Arcana and four suits of Minor Arcana.
The standard deck.
A variation on the Rider-Waite tradition, painted in dusk violets and blues. Filchy launches with this one deck, all 78 cards of it, and lets the art lead.
Reversals
Cards can land upside down, and Filchy reads them that way.
Painterly
Dusk violets and blues, made to lead while the interface steps back.
Or cast the I Ching
Every reading type works with the I Ching too. Cast a hexagram instead of drawing a card, with the text from James Legge's classic translation.
