This is niche, but honestly I search for a lot of magic cards. I get a lot of use out of `!mtg`
That's a good example where I get zero results if I misspell the search term: https://scryfall.com/search?q=black%20lotuss Whereas I Google or Duck for "mtg black lotuss" I'll almost certainly get the correct results. I feel like I'd just get frustrated with the much worse text parsing of each site's search field. Although it is interesting that this "Scryfall" site that owns "!mtg" isn't on the first SERP for Google…
Being able to see price, reprints, legality, etc is great
Also, the best part about scryfall is it's searching paramaters. If I want to see the most expensive red creature cards currently legal in standard, I can do `!mtg color:r sort:usd legal:standard type:creature` and it's right there
It's made building decks so much easier for me with these easy text searches, as someone who loves being able to do things with a keyboard rather than selecting these parameters using a mouse on something like Gatherer
