As the title says, this is the usual baron + mime naneinf, with the exception that before ante 9 you get a natural negative mime in shop, allowing you to keep perkeo in your deck throughout the run. I used perkeo to clone plutos, after i purchased an early observatory
I also used sixth sense for deja vu seal. I got an ecto as well. I had 2 barons and a brainstorm in the early game, i sold the other jokers and i used the ecto that landed on the baron. Later i found a negative mime in the shop, and perkeo from the soul.
I found another soul card for legendary joker in ante 12, but i didn't take it, to make sure i don't mess up my setup lol.
I used DNA to get past ante 32 (the finisher ante), and then i was looking for burglar. Achieved naneinf on ante 39. It was a fun one. You can acheive naneinf before ante 32 as well, but after ante 24, you get the full setup, but i decided to go to ante 39 because it was my first ever naneinf.
PS: fun fact, somewhere along the way i got a negative bull with 10k+ chips
