So Oda went out of his way to make all the important players in Kaido’s crew have their names be card themed, but Oda forgot about the Ace card, the most valuable card? Yamato is obviously supposed to represent the Ace. Denying this is like saying that the Numbers don’t represent the numbered cards just because their names aren’t literally “Ten, Nine, Eight, etc.” Oda didn’t want to name another character Ace since that would be weird, so he went a roundabout way about it by giving Yamato allusions to the Ace card
