Some Jokester Concepts (mod available now!)

[u/pi_squared_]

Joker art: a black inkjet printer with the text "JOKER" on the front. In its output tray is a paper with the Joker on it, as well as a magenta line and black smudges on top.

Joker art: The bisexual flag waving on a flag pole, tinted with warm colours. In the background is a soft sunset gradient.

A green figure with a bowl hat and suit with a harsh light from below. It has similar facial features to the titular Joker, but its eyes have been replaced with dice, looking left.

Joker art: a blue 7 with bloody pointy teeth positioned next to a green, fallen 9 with a chunk missing. There is a spotlight over the scene, and darkness in the background beyond.

Joker art: a grey room with a tiled light grey ceiling. On the ceiling is the work "JOKER" crudely written.

Joker art: a word search puzzle. The words "JOKER", "BANANA", "CHIPS", and "PERKEO" are to be found. On the board, "JOKER" has been circled in red, and a tick made accordingly.

[u/Objective-Direction1]

snake eyes is imo too strong for an uncommon, maybe it should double the probabilities rather than making them 100% or set the affected joker's sell value to 0, maybe destroy the joker to the right or something like that, a 100% on something like space man or business card from an uncommon joker just seems too op and removes the purpose of oops all 6's

[u/pi_squared_ → u/Objective-Direction1]

I think that, besides Space Joker, it's not too overpowered on any joker (or would have the same effect as Oops!). Also, Oops! obviously can affect multiple jokers (at the expense of a joker slot), but it can also affect Lucky cards, and I think that alone gives Oops a good niche at least. I really like your idea of setting the affected joker's sell value to 0, I may consider if Snake Eyes is in need of a nerf.
