I don't get it - you fully cancel the card? Or do you mean you just get the credit card to issue a new one? If that's the case, then I don't the "burner" aspect. That's just normal usage. If the former, what advantage does that provide? Is it not in your name? If there's some fraudulent charge but you just bail on the card rather than go through the normal process, it looks like non-payment and affects your credit.
