Rarity Hub
Mystical Blooks Explained
Mysticals are one of the biggest confusion points in the Blooket collector vocabulary, so this page clarifies what the calculator can and cannot model.

Mysticals are not modeled in the pack calculator because they are not standard pack pulls in the indexed site dataset.
What Mystical usually means
In the collector vocabulary, Mystical refers to a special top-end class that sits outside normal pack grinding. That makes Mysticals a real search topic, but not a calculator target in the same way a Chroma or Legendary is.
Why the calculator does not model Mysticals
The site calculator models outcomes you can chase through indexed pack openings. Mysticals do not fit that workflow, so pretending we can assign them a normal pack probability would make the site less trustworthy, not more useful.
The practical replacement
If what you really mean is “rarest pack pull,” you probably want the Chroma hub. If you mean “highest realistic rarity I can grind for,” the Legendary hub is the better starting point.
