OP17 Green/Black (Brook) Deck Profile

Brook got a small update utilising the mill cards thanks to OP17 stuff. You could use the main 12 cost Elbaph engine for Brook, but you will be sacrificing other cards to fit Elbaph in the build. Instead, I'm only using a few stuff from Elbaph engine whilst maintaining this deck build, so we have enough mill to use some of the cards in this deck. 

OP15 Green/Black (Brook) Deck Profile

We finally got a Brook Leader, I think we are missing Franky Leader now for the Straw Hats. To be honest, I was wondering how do you even pull off Brook's effect, but it seems you don't. It is more about milling cards so we can play those cards from the trash. Although, no idea where the green is from, maybe setting stuff as active, but you do need 0 cards in deck to untap Characters.
