Jewel cards can be acquired with Tokens and Bonuses from the Pyramid.
2. Prestige Points
Once purchased, a Jewel card grants you its bonus(es), depicted on the top right. Each bonus decreases the cost of future card purchases.
For example, by purchasing the card above, you reduce the cost of all of your future purchases by 1 green token, (as seen on the 1. point.)
Some cards have 2 bonuses, thereby granting a 2 token reduction.
It is possible to have enough bonuses to reduce the cost of a card to 0 tokens. The cost of a card may not be reduced below 0, meaning you cannot gain tokens when purchasing cards.
Acquired cards are ogranized in front of the players, sorted by bonus color. Cards may be overlapped to save space. However, the top of the card (where points, Crowns, and bonuses are depicted) must remain visible.
When a card is purchased from the pyramid, replace it with a new card from the corresponding deck, placing it faceup in the pyramid.
Some cards have abilities, that are resolved immediately.
