Hall Monitor card's ability calls its target HIDDEN CARDNAME

**Describe the bug**
I thought this was a weird one at first, but it's probably a trivial scripting goof.

I was in a Shandalar Adventure match against an "Adept Red Wizard" enemy. My [Ugin's Mastery](https://scryfall.com/card/mkc/53/ugins-mastery) manifested a [Grim Monolith](https://scryfall.com/card/ulg/126/grim-monolith) as a face-down creature as I cast [Scrawling Crawler](https://scryfall.com/card/fdn/132/scrawling-crawler). So far, so normal. The bot activated its [Hall Monitor](https://scryfall.com/card/stx/105/hall-monitor)'s ability, with a targeting line at Scrawling Crawler. The stack message said, "Scrawling Crawler gains **hidden cardname** can't block." After resolving, Scrawling Crawler was unable to block and had some rules text added, referring to itself IIRC.

The manifested card was a red herring.
**Turns out the card script literally says HIDDEN CARDNAME.**

I don't know why it says HIDDEN CARDNAME. The oracle text doesn't indicate secrecy, and it'd be weird to not tell the blocking player how they are restricted. Also the targeting line pointed at it.
