In early 2020 I bought this mini collector's album for the basic Sword & Shield set. It's kind of a challenge to get these 24 cards. My challenge however got cut very short due to Covid-19 coming. I'm wonder if there's any possibility to complete the challenge. Here's the list showing you what I've got and not still got.

We have no context. If you're willing to buy them as singles and it's permitted in that "challenge" you signed up for, yes, it is possible. If the challenge is to pull them from booster packs, it's in theory possible, but you likely won't.
EDIT: also, as an aside, the official mini binders tend to be atrocious for card storage. They're better than no protection usually, but not by a whole lot, especially compared to the other options out there.
We have resources for card protection in the rules. :) But of course you’re perfectly capable of completing the collection! Whether you find someone selling a good amount of them in bulk, or buy them in singles, there’s no limits to what you can get (as long as money isn’t an issue lol).
