The dex currently features a list of mythicals that are banned with the caption:
"
The following Pokémon are banned from Regulation F:"
So that would probably need to be updated to say regulation G.
Koraidon: add life orb/close combat as a slash option. With an EUIC win and the amount of burst damage it deals i think both life orb and close combat as options on koraidon have sufficiently proven themselves. Life orb and close combat both overtook clear amulet/collision course in usage at Fortaleza regionals, where at Vancouver life orb overtook clear amulet and collision course and close combat were equal in usage.
Miraidon: Maybe add the bulky set that has been running around recently? We saw some incredibly bulky miraidon at EUIC which were nearing max HP.
Terapagos: add earth power as a slash option instead of the main option and replace the current main option with substitute. At EUIC it already had a lot more usage than earth power (55 appearances as opposed to 33 from earth power).
Lunala: add expanding force/psychic terrain into the analysis.
Ice rider: add tera fairy as an option & fast spread. Optionally the miraidon electric terrain spread (244+ SpA Choice Specs Hadron Engine Miraidon Electro Drift vs. 244 HP / 172 SpD Calyrex-Ice Rider in Electric Terrain: 174-205 (84.4 - 99.5%) -- guaranteed 2HKO)
Whimsicott: add tera dark for the covert cloak set and include helping hand as a slash option.
Chi-yu: remove choice specs (too frail + too little usage at recent tournaments) and remove life orb for the glass cannon set (no life orb chi-yu at EUIC or vancouver)
Dondozo: add solo dozo set (sand tomb/yawn/trappy things): around 1/3rd of the dondozo at EUIC were solo and 1/2 of dondozo at vancouver. Working on an actual example of the saample set currently which i'll link in
Farigiraf: add psychic as a slash option over psychic noise (2hko's amoonguss with less investment/rising in usage)
Iron hands: add tera bug/poison as possible tera options
