Doffy gave his top executives titles linked to the four playing card suits: Spade, Diamond, Heart and Club.
Luffy knows people, who are linked to those four symbols also, but they are not his executives but will have to face execution.
Pica/Ace
Spade Seat/Spade Pirates
Rosinante/Law
Heart Seat/Heart Pirates
The two share a strong bond
Trebol/Barto
Club Seat/Barto Club
Both are former Gangleaders
Diamente/Jozu
Diamond Seat/Diamond Jozu
Kira Kira no mi/Hira Hira no mi
Ace already had to go through execution. The other three will too, but they will be saved. Barto talks about Luffy even more than Ace did and Law is getting beaten by Blackbeard now, just like Ace was.
