The way Oda went with the character, he has very good potential from his monster form, cards expanding powers, calculative, and his predictions
Furthermore than this, he is one of the few characters that may gain some character growth this arc from his perspective of always following his cards to avoid risky situations to maybe ending in a situation where for the first time he'd decide to take risks to grow
Also has a month prediction that will still play a role at one point during this arc imo, with him having unrevealed secrets yet like his curse or ultimate cards, with his arc potential only falling short to Luffy, Kid, Law and Zoro imo
Which is why i'm very interested in the way his development will continue this arc
