That brings up an interesting question. WotC has announced that the Mystic and Artificer will be AL-legal before they are published in a product. Will they be added to this sheet at that point (or will they not be added until they are published)? Right now, this is a theoretical question as they are up on DMsGuild but are not AL-legal yet.
Nope. No Unearthed Arcana data is in this spreadsheet (see the FAQ). Personally, I would never expect any homebrew material to be entered into character generation sheets (excel or otherwise) - some do support personal entry of data (though it is often times confusing to do so).
On a separate note, I disagree that the Blood Hunter is balanced. Do some searching, there are a couple of broken builds that rely on the Blood Hunter.
While WotC has announced they are adding the Mystic and Artificer, we still do not know the final class stats. There may have been changes made to them following their release in UA. With that being said, Forged will only add new D&D material to the CS when it is released in office WotC D&D manuals, handbooks, adventures, accessories, supplements, and such.
Once again....
New material will only be added to the CS, when new material is published in official D&D manuals, handbooks, adventures, accessories, supplements, and such.
As per DMSGuild WotC said the following about the Artificer and Mystic...
"This version of the artificer character class was originally released as part of the Unearthed Arcana web series. This download is the latest version of the character class. The artificer is in playtest. It has been made available so that you can use it in your games and provide feedback on its design."

That means they are not the final versions, they are still playtest material. Strongly urging someone to put something in their stuff to make you happy isn't gonna happen.
