[Bug] Highlighter on Scryfall Syntax not missing cards (Bloomvine Regent on o:basic)

[JPalmerDev]

I have encountered this bug occasionally but only realized it afterward. Caught it in the act.

Bloomvine Regent appears to not show up if you search for o:basic, despite its omen asking for basic Forests.
If you search on scryfall, it does show up: https://scryfall.com/search?q=t%3Adragon+o%3Abasic&unique=cards&as=grid&order=name (added t:dragon to reduce total search results)

This could be just Omens, or it could be multi-cards in general.

This is because you're using the reversible printing of that card, and the issue is that Scryfall doesn't have a card layout for reversible + adventure/omen. If you add is:reversible to your Scryfall query, you'll find they don't return the printing either - instead you'll get Magmatic Hellkite, which doesn't have the Omen that causes the breakage. I think Corey has something planned to fix these, but I'm not sure what the timeline is. Once it is fixed on Scryfall, it'll be fixed on Moxfield within about 24 hours.
