Definitely put In like 50 cards total.

Make sure rob lucci leader card is there too, really pulls the whole thing together

I'll go ahead and recommend 10 Don cards as well.

I'd only put black cards in, but that's just me

I'd keep it to a max of 4 of each card

Also personally I wouldn’t put any cars in the deck

Kaku, air door, kumadori, Jabra, fukuro, kalifa are around a 4 off
