• Sock and Buskin from Judgement from Emperor in Ante 1 Small
• Gros Michel (expires after Ante 1 Boss) from Ante 1 Large Jumbo Joker pack
  • Comes back as Cavendish right before Ante 8 boss
• Hanging Chad from Ante 1 Large Regular Joker pack
• Triboulet from Soul in Ante 2 Small's Arcana pack
• Smiley Face somewhere in Ante 2, which was last second replaced with Cavendish
• Photograph at around Ante 4's Boss shop, but I also did a bit of rerolling when I had the money

There is also a hologram Blueprint at around the Round 37 mark, which you can get if you can buy the Antimatter voucher early.

Played on Purple stakes. Initially played a lot of King/Queen full houses, but pivoted towards 4/5oaK Kings mid-game (around Ante 5 Large). Prioritized Hermit, Magician and Temperance up until Ante 12, as well as bought all vouchers. I was able to reach Ante 16 on my first try.
