Forgive me if I went over these already.
Stock holder:
Similar enhancements / editions can be stacked.
Stackable: Bonus, Mult, foil, holographic, polychrome.
(Theory: gives some obscure builds potential with The Wheel, Aura, The Empress, The Hierophant, etc.)
The Goat: (cannot be eternal)
Sells for a high price (sell price is [sell price] +5$)
Gain +5$ if destroyed.
Effects that target random jokers, will target this joker first.
(Theory: a semi-“econ trickery” joker that also subtly benefits Sacrificial Dagger, Temperance, Swashbuckler, and will also be the first joker targeted by Madness, and by Crimson Heart, also a good joker to sell for Verdant Lead)
Copycat:
Copies enhancement gains from the joker to its left
(Theory: “blueprint” except for jokers that gain chips/mult/xmult/sell value; Castle, Wee, Egg, Lucky Cat, Runner, Red Card etc)
The Veteran:
Aces can be played to complete Full House hands
(And it would also work, suits given, for Flush House Hands)
(Theory: give a bit of fun an function to both Aces (which are kinda poop) and the Full House / Flush House hands (also kinda poop))
Jeweller: (cannot be eternal)
Sell to upgrade held Stone jokers.
(Upgrades are:
Rough Gem: +1$
Blood Stone: +x0.25 Mult
Arrowhead: +25 Chips
Onyx Agate: +4 Mult)
(Theory: I guess just a fun way to isolate these four jokers as a kind of special little quartet)
