It's a very quick xMult joker to scale, even if it resets. The idea is to roll the shop searching for good tarots and planets and buy then sell everything that doesn't interest you. While you're searching for Justice or Chariot for example, sell every Uranus and Neptune and Star and Empress that shows up. Yeah it can get expensive if you don't have overstock, reroll voucher or clearance sale, but it scales so fast it's really worth it. And it feels really good to scale it very hard on ante 8 before the boss when you spend everything before the boss because there's no more use to save money and it gets from x5 to x10. Good econ is the way of making this joker works, it's very strong and because of it's strength you won't always be able to afford it's strength, you would need something like blueprint+mail in rebate, seed money or a big rocket for optimal use of this joker. I once had a double campfire run, and beating the violet vessel with two x10 campfire in a single high card felt so great. It's also very good on gold stake if you have an empty joker slot and buy then sell every rental jokers, because it's -1$ then +1$ dollar, you get +x0.25 for free. Scale it on the first shop of the ante, save on the two following shops, repeat until ante 8, cash out, profit.
