To add on to this, the move dex includes all Pokemon moves except Z-moves, Let's Go Partner moves, and Max/G-Max moves. This includes all moves unusable in Sword/Shield, so having Bank is the only way to get ahold of them(outside of the Gen I moves not in Sword and Shield because all of them are in Let's Go) Additionally, the only way you can get Kyurem Black and White's signature moves registered is via Sketching them onto a Smeargle in Gen V-VII then transferring it to Home(Because Smeargle is not in SwSh, Kyurem is not in BDSP, and neither are in Legends).
Because I am crazy, as of Legends: Arceus I have completed both the move dex and ability dex(on top having a complete National Dex complete will all alt forms except some Gen V-VIII Shinies)
