Storm scale essentially enumerates how likely a mechanic is to be reprinted according to Mark Rosewater (1 = very likely, 10 = very unlikely); see here:

Resolves based on the mechanic with the greatest score as of market creation (the "latest ranking" tab) that is printed, unaltered, on a new standard-legal card (no reprints) before the end of 2025. I will not count silver-bordered/"un"-set or digital-only cards.

I will not bet on this market.
