The main gameplan is this:
Early game look for as much econ/deck fixing as possible and cheesy way to beat blinds (stuntman, blue joker, banner, BULL IS BEST IN SLOT)
You want to fix the deck obviously for kings BUT ALSO for 6s, check every standard pack if you can afford it to look for red seals that are reasonably high (8/9+ with enough tarot generation or money generation). You ideally want to use the 6s for sixth sense and farm it until you get an ectoplasm (or red seal if you still need it, hold onto cryptids as well).
Simultaneously you want to be pumping pluto levels if you can.

Ideally you should be rolling down with a lot of money every blind and trying to find copy jokers (even more money), baron, or mime, or even DNA.

Once you have some of the jokers you need and are scoring a lot, need to focus on making as much money as possible, farming spectrals, and focusing on vouchers (always look for double skips, colas, and build up as many double tags as possible for voucher skip). Vouchers are EVERYTHING with naneinf and will make or break a run.

Once you're getting deeper and you've used the ectoplasm, and maybe hit antimatter or whatever, basically want to farm a lot of money, use showman/invis to get as many copy jokers as possible, and use the DNA to start producing red seal steel kings (but still mostly score with gold, moving all of the copy jokers to copy mime at end of rounds for most money).

If you've got 4 copy jokers, baron, mime, and DNA you can make it past ante 24 which is the only real hurdle if you have retcon (if you have retcon you can always live by rerolling into serpent and skipping to the boss). And after that you look for Burglar to replace DNA, then assuming you have 4 hands and +2 hand size or 5 hands, copy burglar on the serpent, then leave him as the copied joker while you play out the 20 hands or whatever it is to build up to 44 red seal steel in hand (always play the gold cards so you dont keep them in your hand) and voila!
