I've tweaked it a little, and come up with something that I think works, especially considering your desire for fast cash!
I call it the Sgambler deck. You start with the new bauble, Chip Magnet: "Whenever you clear 2 or more chip thresholds with a single hand, gain an additional chip for each chip threshold beyond the first. Clearing them all at once nets an additional 2 chips"
You get +1 chip threshold per ante. So you can effectively make up to 13 chips per ante, right off the bat.
As you suggested, it will not be able to collect interest, so you can spend without worrying. This deck also takes the Piggy Bank out of the bauble pool.
It might be super overpowered, but in games like this, balance is an illusion. Have fun with it. If it's OP to the point of it being the only viable deck, maybe I'll rework it in a bit.
To unlock it, you'll need to purchase the Chip Magnet in another run, and clear all chip thresholds with one hand two antes in a row.
Will be available in tonight's update.
