Matador is often considered a strange joker.
The idea is that you are often flying close to the sun by playing useless hands during a Boss.
It is however, confusingly implemented. And inconsistent between bosses.
I have a few potential ideas for Reworks.
Idea number 1 - Complete rework. Give Matador unconditional income, but add a penalty. E.g.
Earn $8 for every hand played during a Boss Blind, -1 Hand during Boss Blinds
Idea number 2 - Matador stays the same, but it wiggles when the hand played gains income to make it more intuitive
Idea number 3 - Matador becomes a conditional Joker, like Glass or Stone. And will only show up when it has an effect on the next boss. This will make it feel less bad and less punishing when drafted for a useless boss
