Help me make a character to match my dice

Like many of you (I hope), for me the best part of starting a new character is picking a set of dice that matches their theme. Well, recently I came into possession of this super special dice set (look, they Nat 20'd the moment I picked them up, clearly they WANTED to come home with me, don't ask about the price). They're made of a clear crystal, numbers are etched in gold runes, and when the light hits them they burst with prismatic rainbows. Super excited to use them but I don't have a character in mind that fits these dice - what type of character would you create? Any class/subclass that comes to mind? (And yes, they are impossible to read but these are the sacrifices we make)

Thanks in advance :D
