gilded oracle
This kind of joker has become pretty popular, often mocked as a "winless" joker:
"X 3~4 mult, -1X if played hand's score exceeds score requirements"
The problem i have with this idea is that this joker stabilizes at some point, becouse as it lowers, your score does too, until it just becomes free 2~3 Xmult, so here's the alternate version I propose (Numbers might be bad):
"X3 mult
the third time a played hand's score exceeds score requirements,
self destruct
(Currently 0/3)"
This one achieves that same "winless" idea w/o stabilizing the joker in a middle ground but it doesn't make it die instantly, and this could fit for a food joker the same way ramen does, cause ramen can also be permanently maintained
