This is the objectively correct order to put the jokers in. You should be aiming for this exact setup in every single run.

Yes I know, Cartomancer and Hiker should be to the right of the flat mult because Baseball Card makes both give x1.5 mult - I made the decision early on that it's better to have them in The Bluestorm Machine so that their effects can be more easily copied, and it would take way too much effort to rearrange them now.

I'm tempted to make another version of this that ignores Baseball Card entirely so that other uncommmons could be to the left of the flat mult, but again, I (should) value my time, and I don't think Uncle Chaos would approve anyway.
