You get Blueprint super early, don't remember exactly where, but it's ante 1 or 2 I believe. I pushed playing Banner/Scary Face to Ante 4, there you get Brainstorm and Baron at the same time on the base shop. The early cartomancer is useful to start fixing deck and get the early Certificate as well, after 2-3 cards I believe you get red seal queen, just use strength/chariot. In ante 5, don't remember the exact blind(ante 5, round 12 for me), after rerolling 3-4 times the shop you get both hanging chad and photograph, sell banner and whatever is the other joker you have to buy both, then play high card until the mime shows up, to that point you should have a good number of red seal steel kings on your deck, when the mime shows up sell photograph to buy it, always buy the vouchers except planet merchant, with tarot merchant x4 you can reroll like crazy, a lot of temperance, fools and hermits shows up, that's important because at some point I got both dna and showman at the same time rerolling, after a bit I got my second mime then made the baron negative with ectoplasm(get the vouchers, the one that make spectrals appear on arcanas will show up) and finally I got another baron with showman then sold showman to buy it. Now, sadly this will only get you to ante 23, there's a funny thing you can do, once you get everything, start to accumulate money, if you got the voucher then you got the infinite boss reroll, once you reach ante 22, you can start skipping small and big blinds and reroll the boss until you get The Serpent, then just discard 1 card to get 3 until you get no discards then play, that should get your score to around e117, I lost on ante 23 because I got there with $70 and didn't got the serpent, the strategy on that point is to try for another ectoplasm on arcana or spectral, or to get antimatter voucher, but I don't remember any blank voucher, might be wrong tho, the point would be to get showman again and pray for another blueprint or brainstorm.
