Effect	Jokers have a 30% chance of getting the "Eternal" sticker; they can't be sold or discarded.
Difficulty	Intermediate

Black Stake: Jokers have a 30% chance of Eternal. Eternal Jokers can't be sold. Avoid slot-hogging Jokers (Invisible Joker, etc.).

Jokers with stickers like Eternal, Perishable, or Rental appear. Watch for locked slots and economy pressure
"Grab-and-win" Legendaries like Perkeo / Chicot / Triboulet gain even more value
Expand slots early with Negative / Antimatter
