1st shop Shoot the Moon which is in the deck core (first Wheel of Fortune gives it polychrome), early Wrathful making early Spade flushes, early abstract for added mult, also early Mime which is also core to the build. There's also a Photograph early to get some xMult and later on a polychrome red card which you can sub it for. Early in the run scour the arcana packs to put steel on one of your queens run by getting rid of as many heart cards as you can while keeping good econ (saving queens for the mimed up StM and adding gold to some cards to boost econ which works great with mime). Either the 2nd or 3rd spectral pack you see will have a purple seal, out it on any card that's not a queen. Along the way there will either be a skip for a negative which will net you a negative fortune teller, or it'll be there by itself. In a shop at around ante 5 or 6 you'll find a negative Perkeo in an arcana pack, make sure you have room for it. After you get Perkeo you'll be able to discard your purple seal card which will net you a Death card which you want to copy as much as you can and fill your deck up with steel queens. In endless (ante 9 I think), you'll find a skip for a negative which will also net you a negative bull, so make sure your econ is up to spec. Around that time or a bit earlier you'll also find a Swashbuckler which I also recommend you take. You'll also come across a Constellation which will give you nice mult, but later on you'll come across a Steel Joker which, if you played your cards right, should have about x5.2 mult by that time which will only increase. The highest I got was ante 12 and boss blind and just barely missed the mark. Sorry I couldn't remember more details, but I do recommend you experiment with it and see how far it's possible to get. Hope you enjoy!
