Skip the first blind to get alot of money after the boss blind.

For the first shop buy the buffon pack and select "Riff - Raff" joker. Its should give you the "Gross Michael" and "Mad Joker" and after you win the boss blind, the "Gross Michael" should break and "Cavendish" will apear at the next shop. At the same shop buy the "Aracana pack", inside it will be the soul and it should get you "Triboulet". At the same shop, reroll it and you should get the "Sock and Buskin".

And later you bee getting good joker also.
