I think I played it poorly, and had the potential to go naneinf, there were 2 legendary jokers I didn't take as I already was set up.
By ante 4/5 you should have 2x Mine (Invisible Joker), Baron, Blueprint, Brainstorm. Red seal comes pretty quick on king and you can easily have a full steel red seal deck by ante 9/10
You get showman ante 19 (unless I missed one) and can negative the brainstorm for an extra mime and Baron.
Ante 20 is The Plant and I never got the boss reroll token.
