(why I can't do it myself, is cause I'm making a game in a different coding language, and it would be easy for me to mix them up if i was using 2 at the same time)
Following photos are few of my best jokers, bellow descriptions are in the order of images. This is nowhere near all of my ideas, and I'm not planning on stopping making them any time soon.
"Death 13" (Rare) = every not-scoring card in played hand has a 1/4 chance of being destroyed, gain X0.5 for every card destroyed (in any way)
"Dementia" (Uncommon) = ||(credit to "@/furret the hologram fan (8/15)" for the idea)|| random +/- hand size, resets every hand played and every discard
"Jevil" (Rare) = all planet cards are face down, base chips are of the most upgraded hand (doesn't effect scoring or other joker effects)
"Lobotomy" (Rare) = random Xmult every time (from X0.25 to X20, usually around X3-X5 like misprint)
"Big Earner" (Uncommon) = All money sources multiplied X1.5
"Fridge Joker" (Rare) = All decaying Jokers (banana, bean, popcorn, ect.) don't loose power, and do not self-destruct
"Unstable Joker" (Rare) = Every round has an effect of a random Joker (excluding Unstable Joker)
Hope someone gets around, cause i have plenty of good, original ideas not yet revealed to the public.
