This is the part of the DLC I'm most anticipatory of for Smogon. Move tutors in the SS DLC changed the meta across tiers with moves like Poltergeist, Grassy Glide, and Dual Wingbeat. USUM had move tutors increase the distribution of moves like Defog, and more moves were obtainable on Pokemon with every new release. I would be surprised if there wasn't any kind of move tutor in either of the DLCs for SV.The thing I'm waiting on now is to see is movepool changes and whatnot to the 'returning' Pokemon. Is Wave Crash Crawdaunt gonna be a thing or nah?
Plenty of older Pokemon got some new and competitively relevant tools in SV as well, Floatzel getting Wave Crash, Slowking and Glowking getting Chilly Reception, Scizor getting Trailblaze, and Azumarill gaining Ice Spinner. Then you have older Pokemon gaining older moves, like Zamazenta getting Body Press, Garchomp gaining Spikes, and Breloom getting Close Combat. I'm eager to find out how much of a facelift many of the returning Pokemon will get, not to mention the possibility for SV-native Pokemon to gain more moves.
