>any IVs from 1-31 are treated as the full 31
>IVs of 0 stay the same, but you can no longer breed/catch Pokemon with an IV less than 1
>exception is if you breed a Pokemon while holding an Iron Ball, the offspring will always have 0 speed
>Confusion/Foul Play ignores IVs as well
>wild Pokemon now have a random amount of EVs when caught
>you can now get special Bronze, Silver, and Gold balls for Pokemon with multiple perfect IVs (more 31s = better ball)
>Hidden Power removed, Pokemon that need it for coverage given better movepools Fiery Dance Lilligant pls gamfreak ;_;
>alternatively, Hidden Power no longer dependent on IVs, old Pokemon keep their Hidden Power type but babies can inherit specific types depending on what type Plate their parent holds. Otherwise father has 50% chance to pass on HP type
>Nature can be changed by leaving a Pokemon in the daycare with another while holding a Metronome, the Pokemon's nature will then show "[Original Nature], but [New Nature] in battle"
>no max limit on the number of vitamins you can use on a Pokemon, can fully train EVs this way if you have the spare cash
>wings now sold in bundles of 5 at the Battle facilities, specific number of EVs now visible on Super Training screen
>virtually any Pokemon can now be competitive with a little work (barring egg moves and 0 IVs), even old bros transferred up to newer games
