Pretty self-descriptive. Numbers can be tweaked, rarity is whatever.
Kinda anti-synergy with vagabond if you think about it, since it makes you win faster.
The uniqueness comes from 2 mechanics — credit card (with current numbers gives x12 at lowest value, but do keep in mind this is from two joker slots and would be equivalent to x3 & x4), and most importantly, rental jokers.
While it does feel like something that only unravels on gold stake where if you pretty much get an alternative of attempting to minimize the current money from rentals, perhaps it could bump credit card a little and otherwise has a fun interaction with the Tooth.
