(Mainly based off of this old image of Balatro playtesting that LocalThunk shared.)
Add in a rarity system for multiple levels of Enhancements, most of them being bigger numbers, but some also getting some unique effects. Some Jokers, Tarots/Spectrals, Vouchers, and even Decks/Sleeves are added as well, to make full advantage of this system.
Consumables:
The Blacksmith: New Tarot that allows you to upgrade up to 3 selected Common Enhanced Cards into Uncommon Enhanced Cards, or 1 Uncommon Enhanced Card into a Rare Enhanced Card.
Merge: New Spectral that allows you to upgrade up to 3 selected Uncommon Enhanced Cards into Rare Enhanced Cards, or 1 Rare Enhanced Card into a Legendary Enhanced Card.
Vouchers:
Upgrader: T1 Voucher that allows non-Common Enhanced Cards to appear naturally, and gives you a Blacksmith Tarot.
Merger: T2 Voucher that will prevent Common Enhanced Cards from spawning/appearing (using Enhancement Tarots will start them at Uncommon instead.), and gives you a Merge Spectral.
Jokers:
Pixely Joker (Common): After scoring Enhanced Cards 4 times, upgrade the level of the next scored Enhanced Card (Max of Rare).
Grinder ||Grindr|| Joker (Uncommon): 1 in 2 chance to upgrade the level of played cards that are in a Pair and completely identical. (Suit, Rank, Enhancement, etc., and max of Rare)
P2W Joker (Rare): Spend 3$ on a selected Enhanced Card to upgrade its level. (Max of Rare)
Deck/Sleeve:
Focusing Deck: 1 random Suit will be converted to a single random Enhancement, and start with the Upgrader Voucher.
Focusing Sleeve: (Same as Deck on its own).
Stacked (Focusing Deck/Sleeve): The suit's random Enhancement will start out as Uncommon, and start with the Merger Voucher.
