Too many to list, obviously, but they're pretty balanced around the difficulty curve of the game. Ghosts are heavily nerfed (some Pokes lost tons of stats + Spite), and problematic moves (Fury Swipes/Attack, Magnitude, Earth Power/Quake, Powder Snow, Comet Punch, Agility) have been stripped from most Pokemon (watch out for the few Pokemon that still have them haha), and Togekiss has a full level-up movepool.
