Got an early DNA that had a 50% chance of being copied by invis joker (forgot which other one I had back then), used it to clone tons of purple seals to feed fortune teller (only bad luck of the run was no crystal ball or discard vouchers when I could afford), an early hologram from a judgement made this really easy as it gained 0.5x every round from DNA. Round 7 shop had Idol which for me was completely unstickered, Round 7 Boss Blind had 2 of Spades for Idol which were my purple seals, after that it was Ace of Spades which were cloned blue seal iron cards, so I skipped straight to the final Boss Blind.

Seed is S4INQKLR in case anyone's curious
