Got as far as Ante 22, but messed up and killed the run an Ante early in taking an ecto in hope of finding an invis joker.
Baron shows up in Ante 1 shop, 3rd card.
Blueprint Ante 3, 4th card.
Photo/Chad in Ante 7 shop to guarantee a win.
Mime in Ante 12 shop. Showman in Ante 15 shop followed closely by second baron.
Second blueprint in Ante 16, hold showman if possible.
Second Mime in Ante 17. If you weren't able to hold the showman, or you're dumb like me and sold it, you can recover by buying one item from the shop at this point before buying overstock plus, allowing you to pick up the showman again - it has to be done this way if you sold it. Reroll once for the Second Mime. Alternatively, since your score should be good at this point...
Brainstorm early Ante 18 shop.
Negative Burglar via skip tag. Nat negative luchador in Ante 21(?) shop.
A lot of invis jokers popped up for me when rerolling for deck fixing after Ante 18, but no space to take it.
