Ghost Deck
First ante skip both blind, beat the boss blind, get brainstom blueprint. Somewhere along the run you get a pretty early baron and a dna , which then helps duplicate red seal steel kings. I came across this seed without any mods helping, completely out of luck, pretty cool.
(Ghost deck probably a must for red seal, i don't think i saw any spectral pack)
(I can't find the mime anywhere tho)
