Zodiac Deck
Zodiac Deck starts with Tarot Merchant, Planet Merchant, and Overstock, affecting shop frequency and available card slots.
How it works
Its starting setup includes those three vouchers. The source says Tarot Merchant makes Tarot cards appear 2X more frequently in the shop, Planet Merchant does so for Planet cards, and Overstock adds one available shop card slot. Zodiac Deck unlocks by winning with any deck on Red Stake difficulty or harder.
