Play up till around ante 6 normally (be sure to pick up the Sock and Buskin early), then start checking the tarot card packs in the store. You'll eventually find The Soul, which will give you a Triboulet and Yorick. Start converting your cards to kings and thinning your deck with tarot cards. I made it to Ante 26 by finding a blueprint, brainstorm, and then 4 different invisible jokers over the course of the run that turned into another blueprint. Finding a golden ticket also gave me enough money to farm golden kings with gold seals until i had enough money to convert them all into polychrome red seal glass. I was definitely not playing optimally, so im positive you could potentially make it to at least Ante 30 or even naninf as long as you find a way to incorporate other cards or min-max harder than I did. Have fun!
