Trading Card Collector (Subclass?)

Hey all,
I have a new player to DND and they are really into trading card games; like yu-gi-oh. What class or subclass can I reflavor?

I was thinking warlock; every spell is a different creature/entity that she makes a deal with or traps and they have to do her bidding.

Or Wizard. Similar idea to a wand lore wizard but with cards?
