They’d be a new consumable type that directly affects the game itself so maybe one could be use to disable a boss blind and another could be used to add mult to played hand or something

Another example could be earn $1 for each round played

Update to the ideas I have
Shuffle - All played and discarded cards can be played again
Cash Out - Earn $1 for each round played
Red Token - Add 20 mult to next player hand
Blue Token - Add 50 chips to next played hand
Refund - While in shop, undo your last purchase
Now that I think about it this would be better as a mod
safe wedge
So is it temporary boosts?
Tbh I don’t see the use, stuff like Blue Token would be worse than Heirophant, Refund worse than Hermit, etc.
