The Storm Scale is a rating system Mark Rosewater uses to rate the chances of something coming back to Magic. You can see
a detailed explanation of the scale on the Wizards website.
The key things to know are:
- It only applies to the item being printed in a Standard-legal set.
- It's Mark Rosewater's personal opinion, which others in R&D might not share.
- A low chance doesn't mean no chance. Madness returned while being rated an 8.
The data behind this site predominantly comes from the wonderful Storm Scale Database.
