Ante 1: Skip first blind, play second, buy invis joker (Here i bought the extra hand size voucher ), play boss ( Discard all except the spades ) then buy the spectral pack, Ante 2: Skip first and second blind, for the arcana i chose the emperor ( it gives hierophant and judgement) used judgement, then used fool to get another judgement and getting a bull. For the buffoon pack you can chose anything and then sell it. For the boss blind, i recommend using the hierophant with the 10s ( discard everything except the 10s and the 4s ) after the boss blind, do a rerrol, then you get the blueprint Ante 3: first blind, you play it using the 3 10s that appear ( for me that i used the hierophant on the spades an hearts ) after entering the shop, you can sell all the invis for triple blueprint, then buy the space joker, and ultimately the spectral pack that has a wraith that gives you the brainstrom.

TLDR: Triple blueprint and a brainstorm ante 3
