Every deck in the house is cursed.
Five families · one power each

Rarity is rolled per card: Common 70%, Rare 20%, Epic 8%, Legendary 2%. Rarer cards grow the pot faster, and a Legendary spins the Fortune Wheel. You are paid for the risk you take: the multiplier of each pick follows the real odds of the cards still hidden.
The whole table (where the curses sit and every card under every cell) is generated from the server seed, client seed and nonce before your first pick. You see the hash of the server seed up front; the seed itself is revealed when the run ends, so anyone can rebuild the table and check it.
