I've left out the many `NO_MOVE`s. Some of the moves here are taken from [the S/M data](https://www.serebii.net/sunmoon/evolutionmoves.shtml) (like Petal Dance for Venusaur); others are moves that G/S/C Pokémon learned at the same level they evolved (like Thunderpunch for Ampharos); and a few are invented to make up for Gen 7 evolution moves that don't exist in Gen 2 (like Iron Tail for Steelix).

Otherwise, you could be prompted to learn the move twice if you stop learning it the first time. (We do need to allow learning evolution moves and level-up moves separately, since, for example, Abra can evolve into Kadabra at level 16, learn Kinesis by evolution, and learn Confusion by level-up.) +- Two, evolution moves should still appear in learnsets, in roughly the same order as before. This is so that wild Pokémon and enemy trainers' Pokémon with default movesets will still know those moves. + +My solution here is usually to learn moves one level earlier. For example, if Rattata evolves into Raticate at level 20 and Raticate's evolution move is Scary Face, Raticate should learn Scary Face at level 19 instead of level 20. + + +## 3.
