Skillful in the art of magic and card manipulation?
Those are qualifications. Collecting is more of a hobby or something that makes you unique. There's a slight difference. Hope that helped!!
Yeah, the collecting part likely doesn't fit.
"Card manipulation" by itself might describe both magic and cardistry. De'vo is the only one who still sticks with the term Xtreme Card Manipulation, but most cardists thought it was a little too vague to accurately describe their art, and I think they're right. A good sleight-of-hand artist is also manipulating cards, when you get down to brass tacks.
"Card entertainment" is another vague but reasonably accurate term describing both.
You could try "prestidigitation" - it's an older term for magic, but could be applied to any art that relies on using your "digits" (fingers) to do amazing things for an audience.
KPop, why must it be a SINGLE word? I've never known anyone who could use a single word to describe the sum total of their "qualifications" for anything. And while I mentioned it: qualifications for what? A resume or a job application? An application for college? A role in a move, play, TV show or performance art piece? To accurately assist you, we need more information that what you're giving us.
