I actually missed one earlier, Heretical Halation: This is a Twitch Sub drop during the upcoming Dungeon Race. It currently has the Classified images in the API, but we know what it looks like: https://destinyemblemcollector.com/emblem?id=3063212162
And there were a few added that have the Classified images. I've added them to DEC for now, let's list them all out:

Whew, I think that's all of them for today (other than the ones that are incomplete in the API). As always, I'll keep an eye out for anything I missed; let me know if there's anything I didn't catch while looking through the API.
