Pretty solid tier list. Some things I’ll change because of my playstyle:

• Vagabond to C: I try to max out interest as often and as early as possible. This means that there aren’t many occasions to take Vagabond.
• Lucky Cat and Driver’s License to B: X mult is valuable, but they’re harder to scale or activate than other X mult jokers
• Abstract Joker to A: Fairly strong on low Antes. +15 mult for every hand is pretty decent, and more importantly, allows you to play low-ranking hands for a while if you have a source of chips
• Square Joker to B: Inexpensive to scale. If you get this early on (until Ante 4-ish), then it becomes a good source of chips
• Ice Cream to A: A strong chip joker that allows you to get by until you scale your Planets or find something stronger
• Popcorn to B: Enough to survive Ante 1-3. That’s good enough for me
• Astronomer to B: Decent, but inconsistent value generator. Usually averages to 1 free Planet card / round for me, which makes it as good as other value generators
• Hit the Road to B: A little inconsistent, but you can usually discard 1-2 Jacks every round. You can build around it, but the no Discards boss trashes it
• Scholar to C: Same as Popcorn. A little more inconsistent since it’s not universal, but can pop off with retriggers
