I didn't change the learnsets, but there are move tutors. The thing is what they teach is limited (which I should actually include in the walkthrough). If I list what Pokémon can learn from them, would that work? If not, I'll just include it as a document in the next update.
Edit: Now it's in the walkthrough. Here's a quick list: Fire Pledge, Water Pledge, Grass Pledge, Frenzy Plant, Blast Burn, Hydro Cannon, Draco Meteor, Fire Punch, Ice Punch, Thunder Punch, Signal Beam, Iron Head, Seed Bomb, Knock Off, Roost, Pain Split, Heat Wave, Giga Drain, Drain Punch, Earth Power, Zen Headbutt, Hyper Voice, Superpower, Dragon Pulse, Dark Pulse, Gastro Acid, Magic Room, Wonder Room, Stealth Rock, Outrage, and Endeavor.
