Basically I want to list all the moves that have been removed in Scarlet/Violet (even those that are available in Sw/Sh or earlier Pokemon games) and given the following description in Gen 9:
This move can’t be used.
It’s recommended that this move is forgotten.
Once forgotten, this move can’t be remembered.
Please do not count Z-Moves, Max/G-Max Moves, signature moves of Pokemon that are unavailable in S/V (e.g. Aeroblast because Lugia is unavailable in S/V) or moves that have already been removed in Sw/Sh (e.g. Hidden Power, Pursuit, Return), thanks!
