Mod using lovely, made to prove the fact that a gold stake small blind can be 100% unwinnable with imperfect information, and really bad luck
Code is scuffed, ridiculously inefficient, and probably has a bug or two, but works well enough
How the mod works:
Before drawing a card, iterates over each card in deck, and gives it a quality value
Holding cards of same rank increases quality drastically
Holding cards that would make a straight/flush with this card increases quality drastically
Holding cards that have the same suit increases quality moderately
Having cards in deck of the same rank increase quality slightly
And finally, cards with higher rank have ever-so-slightly higher quality
The deck is then ordered, with lowest quality cards at the top
This makes it incredibly difficult to draw any flush/straight/3oak, and makes gold stake small blind on most decks unwinnable (i believe)
The algorithm is mostly tuned for base decks, so non-base decks can exploit it:
Checkered can pressure the algorithm with a billion flushes, causing it to give something else due to lack of options
Abandoned can just reach near the bottom of the deck, avoiding the algorithm entirely
Erratic could do something similar, but i've not managed to get a win out of it (would be easy on 10 of spades seed)
I'm not stating that adding this mod makes the entire game unwinnable by any means, though. There's no 4 fingers/shortcut compatibility, and getting generic scoring jokers would allow you to overcome bad draws easily
There also is probably an exploit where you can get an objectively good draw due to the algorithm being stupider than it should be, but who knows
