The revealer is on point, I like how you included even the non-royal cards JACK and ACE in "royal" themers, so to speak. Great clues for ADAM, UNIONJACK, and LEG (which I got quickly because it's how I clued LEGand ARM in a recent puzzle of mine, coincidentally). I would change the clues for ANNUAL and ARTDECO since they include part of the answers.
I replied to this when it was first commented, but my reply only shows up for me on the device I wrote it, so I'm not sure if you ever saw it. I really appreciate the time you took to comment and make suggestions. I'm still learning the hobby, and I've taken care to catch the same errors in my newer puzzles. Thanks again!
