"This Joker gains Chips equal to the total level of all hands if played hand is [hand], poker hand changes at end of round. "
The concept is a To-Do List for score, obviously playing on the relation between the planets and the various poker hands. Like the To Do List, you could get a High Card bonanza, or it could get saddled with Straight Flush or Four of a Kind and cost you rounds of scaling. It seems flavorful if you can capitalize on the moments when the "planets align" for you, and it seems interesting to empower playing a variety of hands. - Thanks to Sizzle for the scoring idea.
A small observation is that there's currently no space-themed Joker that gives Chips. If this was a Rare Chips Joker, it would make a nice thematic trio with Supernova (Common +Mult) and Constellation (Uncommon xMult).
Potential unlock condition - "Play Five of a Kind, Flush House, and Flush Five, all in a single run." (Available from start all runs thereafter.)
Though it would be necessary to know about all of the secret hands in advance to be able to use it, I don't think it should gain Chips for hands that haven't been discovered on the same run, just so that the numbers the user can see in the display match the amount of Chips the Joker is getting.
