Anyone want to weigh in on how many of those Numbers freaks there are? I'm betting 9 or 10 depending on if the 'Ace' is part of it, otherwise it'll probably correspond to the numbered cards in a suit, 2-10. Don't know if Kaido has his own 'Joker' or '10' equivalent in his own crew or if he allowed the title of Joker to be held by Doflamingo despite not being directly affiliated. He has the Jack, King and Queen accounted for with the Calamities but they're worth as much as a '10' card in most games so maybe there's one more special member of the Beast Pirates that holds a high rank like theirs. Or the 10 would be the leader of those Numbers monsters.
I would count the Ace in. Not only that but if it follows some of the most popular card games world wide, there is a high chance that the ACE is the second in command of the beast pirates. Something similar to what happened with Katakuri being revealed late during Big Mama's arc. We know that the king holds a high position in almost any game, yet hardly ever the king beats the ace. I feel there are characters yet to be introduced in this already packed story arc.
