So I decided to take a look at the movesets of Hoenn Dex Pokémon and see what Pokémon's level-up movesets could be changed. This is based off following criteria:
-Is the Pokémon available in-game? While this isn't always a criteria(see Meditite/Medicham in FR/LG), it is the biggest variable.
-Is the Pokémon available early-game? While not a mandatory criteria, this is increases the likelihood.
-Does the Pokémon learn horribly underpowered moves at high levels? Again, not a mandatory case, but it increases the chances.
-Does the Pokémon get a new Tutor move? Several new Tutor moves have been incorporated into the movesets of Pokémon in the past.
-Has the Pokémon undergone a major moveset change already? Again, this increases the probability, but it is not a deciding factor.
For this piece, the Veekun dex and the Hoenn dex were used, as well as Serebii's B2/W2 change list, HG/SS change list and Platinum change lists were used.
Each evolutionary line will be discussed individually, going with the dex order of Veekun's Hoenn dex. As we don't know what changes will happen to Hoenn dex, other Pokémon won't be playing major parts, but post-E4 Pokémon will be discussed.
It should be noted that these discuss only the level-up moveset. ALL POKEMON are likely to get new Move Tutor moves.
