seed on orange stake i managed to succeed with. mostly playing high cards with a few stone cards (only 2 to make up for an eternal wee joker i found during the run -- without, you'll be able to play 4.)

it is important that you get hologram from the very start, by skipping the first blind and getting the uncommon joker tag -- later on, you should find marble joker; which, compounded with hologram, means you'll be getting +0.25x mult, every blind. it is probably easier to just play out every single blind just for the sake of this, alongside getting any standard packs you find along the way; magic trick will also appear later on before ante 8 iirc, so grabbing that can be helpful to add more onto the giant pile.

by the end of the run, with all the spectral and standard packs i opened, i ended the run with 9.75x mult. i sold marble joker before the final ante in exchange for brainstorm since it seemed like the viable option given the last threat was Crimson Heart, which seems to have paid off. maybe there's a better option before then?

final joker layout consisted of hanging chad, wee joker (eternal), sly joker (eternal; only got it really early on for desperate chips -- definitely find something better), brainstorm, and hologram. you can sort around brainstorm during Crimson Heart for better choices -- hologram ended up getting disabled early on so i swapped hanging chad to the first slot during that point. the optimal layout when everything isn't disabled, for me, was hologram, hanging chad, wee joker (eternal), sly joker (eternal), and brainstorm (eternal)
