Pokémon that would normally need to be traded to evolve now have an additional evolution method. Also, Eevee no longer requires a moss or ice rock to evolve into Leafeon or Glaceon, as these are located far too late into the game. As a quick summary, Pokémon that don’t need to hold an item when traded will evolve via happiness, while those that do need an item will evolve by simply using the item like an evolution stone.

Eevee => Glaceon: use a Shiny Stone
Eevee => Leafeon: use a Leaf Stone
